If mining pool operators became LN hubs right now, there would be two massive lightning hubs. Even now, lightning could be considerably decentralized, but the majority of people choose WoS or Alby because they make everything so much easier. Drivechains could potentially increase node costs, but if the prices are not worth it, then they can do blind merge mining. In most cases, the prices would be worth it because the fees would cover the costs. Michael Saylor has said if we want privacy, maybe we should buy Monero. He seems to want Bitcoin to be a legal, surveilled, expensive rock that we can cash in for CBDC tokens. I would guess a majority of bitcoiners won’t use a sidechain unless they feel comfortable. Imagine a sidechain with the privacy of Monero or zcash, with a slightly increasing blocksize based on Moore’s law; just for spending money. This would let us all run a node while it becomes too successful to justify theft, and Layer 1 is ossified and protected from more stupid shit like Ordinals.
