Bitcoin lacks a real world use case that cannot be realized by existing payment networks. There is no instance where Bitcoin is easier and more convenient to use than traditional remittance networks or fiat. Simply put, the world does not NEED bitcoin. The best we can hope for is a collapse of the world bank but until then credit cards and banking instruments remain easier safer and more convenient
Saying that Bitcoin lacks a "real world use-case" is rather obtuse. You could say that free speech isn't really needed, all people need to do to speak in public is have their speeches pre-approved, and of course the content censored if it treads on nationalistic style parameters.
The system you laud is a system of meddling and control, and by ceding that control over to such a small cabal of politically connected people, you're essentially saying that freedom has a price, and the price you are willing to pay is using PayPal, Banks and all of the other services that have you by the jugular. Naturally, the guilded cage doesn't always make the songbird not sing, so while you sit there swinging and proclaiming how well its going, you're failing to see the overarching point -- you aren't truly free, financially speaking.
Try taking all of your money out of the bank, just because you feel like it. See how fast you run up against "safeguards" that are primarily there to protect the banks, not you.
Try spending your money on something that is considered politically unpopular.
Getting the point yet?
The real world use-case is financial freedom, and that is precisely what Bitcoin represents.
Or stay in your golden cage, singing your song...
