Not "everyone," but yes it would appear the majority of it is highly grifty and most people are in it for the grift, as are 99.9% of BRC-20 token makers/minters. Here's one such exception - this is cool AF - a working chess game as an inscription:

There's a lot of innovative stuff happening on ordinals but we don't hear about it cuz there's no money in marketing it.
They have already... Topps, which was at least at one time the biggest sports card company in the world, started releasing cards on the WAX blockchain. It flopped and they moved to their own private ledger system.
An Ordinal is an NFT, as defined by their common users. Name registrations on Namecoin and fungible tokens with pictures are also NFTs. Sorry, I don't make the rules.
Ordinals users are already blockchain users. They're not moving to a private system. That's for newbs still making the jump from physical to digital.
