OP return size doesn't affect UTXO bloat, which was/is the biggest issue. Node-level filtering doesn't realistically affect what gets put into the timechain for consensus transactions that someone is willing to pay for. So I think those who are concerned about those issues and are bearish enough on monetary transactions (i.e. they don't think they'll price those other things out over the long run) should focus on consensus changes. Those likely won't get anywhere either, but it would be less performative.

it's not about it being fine or not. Of course it's not "fine". The question is, is the countermeasures effective or not

Lyn..tons of respect for your intellect But don't you think it is hard to appropriately price storing data FOREVER? The issue is fiat agents can bloat the network with NFTs and pass on the fiat mispricing to node runners. The OP RETURN debate can be a bit of a red herring bc it does not adequately address the root problem. BUT there is an unadressed problem introduced by ordinals and it HAS to be addressed. Filter afficionados are directionally correct.

The core Devs don't think there needs any countermeasures.
