I disagree. I think users should have the freedom to choose what is defined as Bitcoin. You don't use Bitcoin just because Satoshi said so; you use Bitcoin because you stand with the rules that governs it (21mil coins, non-reversibility, etc). Having a fork such as the one that you have described would definitely not be unpopular but people can just continue on the fork that doesn't implement the fix like how Bitcoin Cash is formed.
It seems that it's just my opinion, but I don't believe that users should have the freedom to choose what is defined as Bitcoin. They have the freedom to experiment with it, to use it, to create new things on top of it, but not to change it. Satoshi chose these consensus rules and every person who refuses to accept them is free to follow a different chain.
As for Satoshi: It's not the fact that a "guy" decided what rules should be followed. That doesn't sound good. It's just the way the chain started. Every consensus change would be against the philosophy.
