Then the world would laugh and quietly ignore such nonsense.
But worry not, such craziness won't occur. It's not under anyone's control except consensus of the community.

But big investors already articulated their interest: they want BTC to be inflatable. Reasonable, but inflatable. Something like: yes, BTC is great, innovative technology, but in order to make it useful international currency, it needs to be inflatable. Say, 1-5M bitcoins a year. The general population ("the community") will eat this no problem. Early adopters will be pissed off for sure, but they are in minority.
