Nobody is forcing anyone to use Bitcoin. Different people have different motivations for using it. Some use it for making money, some use it to be free from government restrictions on money transfers, some people use it to protect their privacy when making embarassing purchases, some use it because they don't like their purchases profiled by numerous companies they'll never hear about, some use it for political purposes and so on. The free market will decide its future. The government will try their best to regulate it but they'll fail because you can't put handcuffs on an invisible hand. Globalization can be the result of widespread adoption of new technologies but it's not necessarily the intent.
