It sounds as if you don't think that it is possible to genuinely not need certain things.
If I don't own a TV and never even remember the fact that I don't have a TV, is that 'attachment'?
I'm talking about the two other cases - I must own X to be in state Y, or I must not have X to be in state Y.
People set themselves up all sorts of artificial success milestones with stuff like this that are just as ineffective on either end of the scale.
My own anecdote. I had a TV, I decided it was a distraction and owning it distressed me enough that I gave it away. I now own a TV again, it's dusty and gets used once a month. Nothing inherently different about the TV in this case, I just matured enough to be able to balance and manage my time better, so now there's no particular attachment (in the case of the TV) to having it there or not.
I was down to the point of it all fitting in the boot of a sedan but had no rhyme or reason to it at all, I was just acting out against a bunch of other stuff because I figured once I was done, I'd be "ready"
_that_ is an artificial milestone.
Personally, I find that going through periods of scarcity provides unique benefits because it proves, without a reasonable doubt, that it's possible to do so. Once the possibility has been witnessed, it is easier to say no even when the object is directly in front of you.
If you are compelled to blog about it incessantly and preach it as religion, yes. Otherwise, not really. The blog post is aimed at a certain type of people and mentality that personally drives me up the walls. The "minimalism"/paperless craze is one of the biggest at the moment.
This is summarized in a great atheist joke:
"How do you know someone is an atheist?
They tell you."
