This is a fun thought experiment and I’m kind of surprised Discovery didn’t do something like this with holodeck tech in the “future” since the writers weren’t afraid to do other tech-taken-to-natural-conclusion like tiny phaser transporters (or whatever those were).

They kinda did, they just didn’t go into detail. There were ships that were made entirely of holodeck at the new federation headquarters in discovery season 3ish, we just never got beyond being mentioned briefly and people going ‘Oh, thats cool’.
