Yes, it's not a good argument totally unsupported. You can live in a society and still criticise it, if there's no reasonable choice to do otherwise.

The thing is, I really like not having to weave my own clothes, or do whatever trade was made obsolete by all the technologies since. I'm guessing OP does too, and there's no good reason to place a cutoff on that at 2020.

If OP thought things would genuinely be better if we went back to medieval tech, this would be a different, and actually much more interesting conversation. As it is, they just didn't know the history.
