Everyone could always learn woodworking, weaving, sewing, smithing, ... that is not an argument. The point is that better tools make it easier to learn/perform/perfect these skills. Today anyone with a little torch and a hammer can play around with steel. 300 years ago you had to at least take on an apprenticeship to ever get to do that. Sewing with a sewing machine is so much faster, there is not much time to invest before you can make your own clothes.
Not everyone has 100s of hours free time to sink into this and that skill "the purist way". Any tool that makes the learning curve more shallow and/or the process itself easier/cheaper/... helps democratizing these things.
You argue as if everyone needs to be a super duper software architect, while most people just want to create some tool or game or whatever they think of, just for themselves.
