Bitcoin is not only a vessel to store value but it's also really useful in the remittance industry. I can send 100,000$ paying a mere 4$ in fees with Bitcoin while it would cost me 3000$ with PayPal and I'd take some risk to do the paypal transaction while doing the same thing from a traditional bank would cost some money,time & would probably raise questions.
This is a major point of
why someone would use Bitcoin over something like PayPal... the main benefit one gets out of using something like Bitcoin is that it is not susceptible to censorship. If someone wanted to make a better life for them self, come to a 1st world country, and send money home to support his/her family; then he/she doesn't need to rely on a centralized third party like Western Union to bone them on insanely high fees and possible censorship if they feel need be.
There are a whole bunch of other examples where bad things can happen if a third party censors someones spending and transferring of wealth.
