I too value my time. And yes, MacOS or Windows allow you to be productive almost right away compared to say Arch Linux. Compared to something like Ubuntu, I'm not so sure. And things which I use daily don't seem supported on Windows (using the GPG app on my Yubikey for SSH access).
But this is just an upfront cost. With Windows, which I've tried to use regularly, there are many annoyances which introduce friction in the day to day. So the "opex" if you will is much higher.
Just this morning I started my Windows machine to play a quick game and wanted to check out something on the internet beforehand. It started bugging me about some "recommended browser settings" in some Edge window that showed up half off-screen that I couldn't move. Then there's the Windows Terminal app which sometimes takes forever to start up. And windows that pop up and look active but aren't.
Then there's a bunch of other little annoyances which I now forget but over a work day end up aggravating. Of course, YMMV as they say, and I know people who aren't as bothered by those. But in case you are annoyed, the upfront cost of setting up your Linux DE just right may be cheaper in the long run.
I've spent a while setting up i3 a few years ago, just out of curiosity. I had been a MacOS user at the time for a very long time. But then something happened, and it grew on me. Now I only use my mac from time to time when idly watching a movie in bed, because I find it slower to use. I hate having to hunt around for windows, move then around, click on some Dock icon which sometimes doesn't show, others shows up while it shouldn't (in the full-screen Mail window usually).
I guess the point is that different people have different needs and are willing to pay different prices for those. There's also a case to be made about high upfront cost + low maintenance vs low upfront cost + high maintenance.

Well, of course. Only issue is how you define quality, as related to what you need. For me, the price of the Windows license was lumped in the same bin with the GPU. Have to buy it to be able to play a game I wanted to play. But I'd feel robbed if I had to pay for it and than have to use it for my job. In my case, I haven't looked under the hood of the Linux kernel or the DE or the terminal app or anything, for that matter. It just works better for me. And I'm also OK to invest some time if it means I'll be more confortable down the road.
