Best example: massive increases to the blocksize.


With small blocks and conservative blocksize increases, Lightning is much more conducive to a decentralised network topology. And at the end of the day, as long as the blocks are small enough for any small business to have sufficient cash flow that they can run their own hub, then that's exactly what small businesses will do: be their own bank. Business people instinctively want control over their livelihoods.

Whereas the alternative is the various Bitcoin takeovers (that never seem to quit with new coup attempts, disguised as a "technology upgrade"), which all mysteriously give all the control to miners by design (did I mention that the miners always push the community to adopt their wonderful takeover plan?). Lightning could end up like that, but doesn't have to be, if the blocksize stays conservatively small.
