Like obscure results in computer science, few will bother to do so. Of those few who do, even fewer can translate it into something that has any impact on the general populace.
Dali was one of the few surrealists that connected to a large audience. Kandinsky is one of the few Bauhaus people to produce art accessible to a larger audience. Andy Warhol left a huge impact on the public as well - but again, not many pop artists did. All the above qualify as modern art, and all of them are approachable to a wider audience.
I'd argue that we see the same in CS. And I suspect that "approachability" is a function of time - we forget about all the ones who had no success, and remember the ones who did. It'll be interesting to see what people say about modern art 100 years hence.
That said, what I find approachable is not a terribly important criterion for art, I just found the it irritating that the actual art was in the process but the context of being in a gallery suggested that the artifact was the art.
(For what it's worth, I also find theoretical computer science papers that produce unimplemented and likely unimplementable algorithms which shave log factors off existing bounds irritating as well, but that is again a matter of personal taste - those at least might give some later researcher a hint about how to actually build a usably better algorithm, though.)
Thesis: if you did decide to "engage the field" of modern art, it would take about a year (i.e. equivalent of one serious college course of two semesters) plus intermittent reading from a popular journal such as ARTFORUM to stay current.
Furthermore, what is unapproachable about a collection of furnace ducts? It's not to hard to understand. Just a pile of ducts. Does art always have present you with a puzzle to figure out, or contribute to some theory? Why can't I say "Look, a pile of ducts. Neat, huh?"
The thing is, we agree that there is music and there is noise. People draw the line in different places, but we all agree that it exists. Why is it that I can literally shit on the floor in front of you and when you yell "what the fuck is this?" I can answer "it's art" and have the audience go "oh, he's good!"? Is it perhaps because, no matter what, I can say that my brand of art is just so new, so advanced, that nobody has understood it yet? Then have some PhD candidate years from now write a dissertation on how I managed to portray the human condition to validate the shit I put out.
Wow, that turned into a rant...
What's important is that you don't have to like art. If it evokes feelings in you that you don't like then just stay away from it. Appreciating art is not a contest. If someone expects you to appreciate same art as them that's their problem with expectations management not yours with performance. I would come to hear you play but if your music would invoke feelings in me that I wouldn't want then I'd leave. Some other person might like the chaos brought by lack of skills crossed with enthusiasm.
The problem starts when people start talking about art ... they say dumbest things and often get away with it.
Basically, unlike what your definition suggests, some art is objectively better than other. Some art takes more skill and invokes more and better feeling than other. Take a look (ideally in person) at Rodin vs Shapiro's work. See which makes you feel more and more intensely. Modern artists substitute enthusiasm for skill way too often for my taste.
I agree that some art can be in some sense better than other. But the only thing you can do is gather statistics about what feelings and how strong any given piece invokes in some population sample. But feelings don't have clear definition of better. Also statistics doesn't have it either. So even objective comparisons are subjective because you have to subjectively choose what you objectively compare.
And I'd love to see you play guitar and sing. It may not be "correct" by contemporary standards, but if it's an honest attempt at expressing yourself, and I enjoy it (I personally love to hear bad singers), then why not?
I'm less interested in the skill than the beauty. But that seems to be missing from a lot of modern works. I don't want my art to be political, or self-aware, or even particularly thought-provoking. Or at least, I don't want it to sacrifice beauty for those goals. Random paint splatters are, I think, less beautiful than Raphael's frescoes.

You can, but I see equally appealing piles of objects every day on my way to work. If something's worth elevating to a gallery I'd expect it to be better than the things I see out there in the world - otherwise why bother with a gallery at all?
I worked for a long time around 1960s/1970s abstract art. Much of it was of questionable quality in my eyes, but there are some really amazing pieces that really make for amazing and beautiful spaces.
My beef with the abstract stuff is that it seems to cut off the oxygen for everything else. Art is fashion, and the patrons of art tend to be fashionable people.
As a more realistic example, many naturally-occurring things (trees, mountains, women) are beautiful but are most certainly not "art". So I'm not sure what the real debate here.
As for furnace ducts: sure, you can say "look, a pile of ducts!" You can say that for anything. You can follow me around all day and point out random objects and say they're neat, and heck, I'll probably agree with you the first couple of times before getting annoyed. But it's like writing a book consisting of only one word -- it might get you a press release, but nobody's gonna buy it.
Skill in anything is just a way to screw probabilities in your favor. I am a computer programmer, not a doctor but it is possible that I might be able to save somebody by doing surgery - it is just more likely I kill them, but a doctor would be able to do it safely.
It would be possible for my grandma to write program to do something useful, by accidentally slamming some keys, but I can do it deliberately, time after time after time.
In your case the problem is that there is no objective definition on art, and as such everybody can consider themselves an artist, which means that skills are meaningless (remember a skill only screws the probability of success in your favor, which is meaningless if there is on definition of success).
Everyone can consider themselves an artist. And you're free to despise all but the ones you like.
