Agreed. There are valid use cases, but ordinals are just ruining the chain capacity. That said, I imagine this is more of a short term concern than a long term one - bitcoin's usecase as money will push ordinals out the market at some point in the future.

There are usecases for custom fungible and non fungible assets. Those should be handled by highly efficient protocols like Taproot Assets. TA and Ordinals work in far different ways. TA can settle any number of custom asset transactions onchain in a single small Taproot transaction. One UTXO. If Ordinals move to this more efficient mechanism, either by choice or being forced to by the market, their small usecase would have a representative footprint on chain as well. But then a lot of the current users are grifters who are likely lazy and won't actually move until the fee market forces them to.

I would recommend moving smaller UTXOs to higher layers however, as fees will continue to increase and your 100ksat UTXO will become dust in that practically guaranteed future environment.
