This is true, and the most practical reason Bitcoin may be superseded by a crypto currency that has an adoption curve similar to this.
What mechanisms exactly would appeal to enough people, so that they would trade the guaranteed-less-than-100%-ever-more inflation of bitcoin, for something which cannot markedly appreciate in value over time, due to new creation tied to increase in userbase?
No trolling, but I can't currently see why anyone with a capitalist mindset would go after that with anything more than peanuts..

Those with a capitalist mindset tend to be those with the most money and power to make things succeed.
