I don’t know why you seem to think suddenly everyone will be masters at decorating and it all will be uniform and boring. Look at the Sims. The majority of players are still basic builders if they even bother to build at all. They can download other people’s builds or not bother. Many are also decent and skilled. Yet that doesn’t stop the genius builders and designers from creating beautiful and much more impressive things. And seeing their builds inspires others to try because anyone can start with the same available tools.
