Creating art for yourself is a fiction. Doing nearly anything for yourself is a fiction. As much as some feel they prefer to be alone, noone lives in a bubble.
When you talk about barriers to entry for art, you really mean high quality art. Sure, perfectionists will be able to outdo their outsized expectations of themselves, briefly. The barriers to making art have been incredibly low for all of human history if you really are talking purely about the cost to begin making art. You and I can start cresting art with our hands right now. How much lower can the barriers be?
It seems to me you would find it easier to work on your perspective that prevents you from enduring the failure required to learn high quality art than to advise we steal all art globally and historically, combine it into a program using the energy of a large nation, and present it to you at your home over the internet.
But like you said, we all have our perspectives on what is important.
