New BIP:
incentivize financial transactions and dis-incentivize non-financial transactions.
1. Find a heuristic where the basic "bitcoin transaction" is identifiable. This is defined as "bitcoin transferred peer to peer with no alterior motives.
2. Charge the minimum for these transactions.
3. Charge a premium for any non-transaction related data. (this definition is where my "im not a LEET bitcoin programmer" will show) But I think "op return" and "<whatever causes inscriptions>" should pay a premium. Lets set this premium at 10x. And this could be adjusted similar to difficulty, but in inverse proportions. So if fees are low, then the premium is 100x. If fees are high, then 10x, since they are probably priced out anyway.
This, to me, is a win-win. There is no "filtering" or "censorship" to be accused. This aligns incentives to eventually price out "non-peer to peer bitcoin transactions" when fees are not stupid low. But while we wait for fees, the non-financials are dis-incentivized as they should be. This "calls the bluff" on the core devs who say they are on the same side and want bitcoin to thrive in the "peer to peer bitcoin transactions."
I don't think this is the reality, so call their bluff. See who's swimming naked.
