If we cap the number of UTXOs then we cap the amount of people that can have their own private key in bitcoin.

OP_CTV actually allows for the ability to share UTXOs, scaling the amount of people that can hold their private keys several orders of magnitude.

As far as Ordinals goes, when fees reach a threshold deemed too high for the market it will calm down. The market clearly has decided fees aren't too high yet, patience.

Personally I spend my time researching tech that will allow more people to use bitcoin rather than worrying about short term flee fluctuations.
