Absolutely. Why go through the banker's system when we can do cash. No fees, instant settlement, bearer asset, perfect privacy... If cash was a coin, it would be an awesome one.
And, at the same time, we must start offering our products and services for Bitcoin and get the circular economy rolling. I'm doing my part with a little Bitcoin Only store ( camisatoshi.com ). Sometimes I feel stupid not accepting fiat, but when a bitcoin sale goes in, it makes my day and faith shoots back through the roof.
