i want to use bitcoin like money without such hazzle (eg moving them to my local wallet first, probably use a mixer sometime in the future).
if we want adoption: how to explain such things to average people?
There isn't much hazzle if you use your own wallet/client (I use blockchain.info and electrum), I buy from exchanges and seldom sell bitcoin. There is no hazzle and fungibility issue. A huge problem will arise if merchants and exchanges starts to refuse "dirty bitcoin" deposits. I hope that day wouldn't come.
