They can pay high fees, just not for an extended ammount of time, because the payment would be higher than the ROI over time, in fact inscriptions died of a lot since their peak. what we can't say is fees handle it and they say making them pay more does nothing, either fees handles it or they don't. The problem is the incentives, segwit gave data a 75% discount, taproot gave 4MB data, and now more data space in a block with op_return. I'm not saying bip110 is the solution to all evils, but we need to change the incentives and make data more expensive than it is now.
