Have you ever tried mailing a dollar to Antarctica. *By snail mail*?

What would be faster? A dollar shipped physically to Antarctica or a Bitcoin transaction?

Your comparing a currency to services that use currency.

Paypal isn't a currency, it's a service.

Similarly to how something like Western Union isn't a currency either. 

Bitcoin is just a currency, it's only as fast as the service that delivers it.

The bitcoin network itself has been really fast for me.  Higher transaction fees equal faster delivery time.  *It's not fair* but it's not so big, a problem that it's worth caring about on my end.
