I’ve found it easier to tell people 21 million coins can and already has actually changed (eth, bcash, dogecoin, etc)… but in doing so, that creates a new “blockchain”. No need to go into detail of forks beyond that.

The hard part for the people that change the supply is convincing people to use their new version. There’s no financial incentive because the supply cap is what guarantees ngu as more people adopt.

Idk if that’s “easier” but more people seem to catch on when I explain it that way.

Tldr: changing the supply creates a new “blockchain” and it’s already happened hundreds/thousands of times.
