then your not explaining it properly. when i tell people that when using btc for online shopping it is impossible for your identity to be stolen they get interested in how and why that is true. then they see huge value. keep in mind many people open credit cards JUST for their online shopping, so its easier to see if something has gone wrong sooner, and to limit risk to that account. thats signing up for a lot of extra cost just to protect themselves. the people i talk to are smart enough to see how much money this fact alone will save them. i generally dont even bother telling people about the other benifits because at this point they are asking how to buy some.
Well I follow the offical wiki guidelines:

People see it as more hops to jump through. They would rather just login into Paypal, job done. With the added benefit of someone to fall back on if things go wrong.
