They are more familiar with the current system, but after you have done it for the first time, you realise that electrum is actually way easier than banks. People just think its harder, but it is not really.
Oh? Something tells me I can't write a Bitcoin address on my direct deposit form.
Seriously, the interface provided by Citibank is pretty freaking great. I work, I swipe my credit card places. As long as I do the former more than the latter, I don't need to touch anything else. Also every few months I accumulate enough points to buy something on Amazon for $50-$100 for free.
Bitcoin could be even better if I got paid in Bitcoin and could pay people in Bitcoin, but I can't.
I had to physically go to a bank and talk to people to set up my bank account. I don't see how that can be considered more convenient than spending 5 minutes on a website.
I think a lot of people would argue that sticking with their current system (banks, fiat currency, etc) is, in fact, much easier than that.
