The part that still baffles me is that if you did that, the NFT community would just say "oh well that's not the REAL owner!" and pretend you don't exist

Similarly if you "stole" the blockchain receipt of an actual NFT, therefore gaining "ownership" of it, the NFT community would simply pretend the person you stole it from was still the "real" owner, despite having zero "verifiable" status to it, beyond having possibly tweeted it before you did

I have to use a lot of quotes because even in a hypothetical there's so many variables that applying real world properties to just make my head hurt

You can't steal a blockchain receipt. Here's a challenge for you: go right click a CryptoPunk and save it, or use this NFTBay to torrent the JPEG yourself. Then try and sell it.
