Bitcoin is not one entity. When someone effectively "creates money" then of course there's a strong incentive for people to build businesses around it.

Things can fork as much as it wants: Any alt-coin that becomes successful will attract people trying build businesses around it.

If you want to prevent people from making money on it, find a means for people to achieve their goals without exchanging anything that can be converted into money. Good luck trying to do that without also making it pointless and/or unusable.
