Global adoption is the common term used by the users not because it will be literally used by everyone, but because it will be available to the most part of the world. Global adoption has its pros and cons. Bitcoin's adoption would lead to bigger community that will benefit most users because there will be more investors pumping the market. On the other hand, this may also cause to a situation wherein the government would try their chance to regulate it.

Personally, I want bitcoin to be mass adopted so that many people can be aware and benefit. You see, bitcoin has so many features that central banks don't have such as having decentralize nature, anonymity, high security, and so on. In addition, it is a good investment vehicle and a medium of exchange as well. I want other people to experience what I enjoy, but of course, only if they want to.

Regarding the issue about those people pushing global adoption for additional wealth, I just want to say that not everyone is like that. Sure, there are people using the opportunity of pushing bitcoin's adoption for their own benefit, but it shouldn't bother you much. It's not as if they are stealing something. They are just promoting and utilizing their resources. I think it's a win-win scenario as long as they're transparent to the future users (that will be generated from global adoption) about the risks. After all, it's not always about the money alone.
