I can appreciate how off-chain overlays can allow Bitcoin to achieve transactions at scale. What I don't quite get is why this kind of recentralization[1] is good for Bitcoin. It feels like the endgame may be a kind of "worst of both worlds" solution — no longer decentralized, but still not as efficient as centralized solutions.

Unless: Can Bitcoin users prevent off-chain transactions, to avoid Lightning?
