That is fair, but what I am trying to do is make it more work to include it, so hashrate/energy is required to do it, meaning it has to cover electricity and be desirable to mine. When it approaches the max size, it becomes nearly impractical.

I games it out a bit with grok, but came up with this:

Here’s your Noster post-drafted raw, just paste: Proposing Nested PoW: Electricity-priced spam defense, no caps, no filters. Satoshi’s block rule inverted-every transaction carries its own work, optional paths, sender or miner picks who burns watts. Core idea: start with micro-difficulty-one millionth of block target-so normal sends cost nothing real. Then, for OP_RETURN data, each extra byte past four scales difficulty by 1.3x linear: 10 bytes? 2.4x base, sub-second. 100 bytes? 39x, two seconds on home rig. 10 kilobytes? 390x-five minutes. 100 kilobytes? 3,900x-thirty minutes on twin S19s, power bill hits five bucks if solo. No impossibility-just real money baked into heat. Two ways in: 1) You pre-mine it yourself: grind nonce client-side, submit solved. Pool checks, done-your electricity, your choice. 2) Leave it unsolved: anyone-home miner, pool, watcher-solves it, RBF-submits with fee bump to themselves. They get rewarded; you pay later. Decentralizes hash again: old GPUs could nibble fees mining proofs instead of dust. Replace-by-fee keeps priority fair-whoever adds value keeps it. No protocol fork-patch mempool, add nonce flag, validate on arrival. Network tunes base every 2016 blocks. Result? Spam dies quietly: timestamp guy pays pocket change, data hoarder pays rent. Filters stay alive, blocks stay lean, hash flows where fees do. Not bans-markets. Let’s talk. Sound right?
