question is what will the market do with a bitcoin that won't change? i don't think it's gonna put up with it forever.
Bigger blocks may be better than no change, no change is better than Segwit.
No change is the safest outcome.
Bitcoin should be a safe haven to store crypto wealth, and no change should be preferred over all the other outcomes.
Bitcoin works great as a crypto reserve and crypto settlement network, it has proven to be safe and should be left alone, except bugfixes.
There is a bunch of coins that developers can use as testing ground for their innovations, Bitcoin is just too big for that, too big to fail.
