An off-chain layer for NFTs, with Bitcoin as the settlement layer, will be actually be the most ideal conclusion for the "Ordinals Drama". It's going to be more efficient, cheaper for users, and developers could actually build "trading" apps using them because transaction throughput will be higher.
That's assuming that's what they want. 'They' being the creators of Bitcoin blockchain bloat and spam. I don't think they are interested in moving their activities off-chain.
I'm assuming from the viewpoint that capital is limited, and Bitcoin = Capital. They either run out of capital first by doing expensive on-chain transactions, or they are going to start to do it more efficiently and cheaply off-chain.
Plus I believe we could also assume that that many of "those" users want cheaper transactions as well, and that they would accept the trade-off of having lesser security to have cheaper transactions.
I am ready to be proven wrong, though. I think making the Bitcoin blockchain congested is one of the goals, aside from tricking a big enough crowd that the inscriptions have a value. They are trying to prove a point by saying, you didn't want a bigger block size, so enjoy our Ordinals on your low-throughput network.
There "could" be some entities that "could" use Ordinals as an attack vector to spam the blockchain, and make it congested. Good luck to those entities, and let them burn though their capital. The miners + a small group of people will make money, 90% will not. It's simply not sustainable plus it proves that the system works.
