I'm involved with a VPS hosting company called ChunkHost, and we've accepted bitcoin for many years. We're not criminals, and we don't tolerate criminals on our network, and nonetheless bitcoin has served us well as a means of payment. We've written on our blog[1] about how bitcoin payments are 20-30% of our revenue.
Another interesting company is purse.io -- they let you get something like a 20% discount on your Amazon purchases by paying in bitcoin. coffee.foldapp.com lets you get 20% off your Starbucks purchases by paying with bitcoin. Again, this is not a scam -- I use it and it works. Don't you think this is a real benefit that real people could appreciate?
I'm curious how long you've been following bitcoin. I've been interested in it since 2009/2010, and have seen the goalposts move a great deal: every time a goal is reached, the critics change it so they can declare bitcoin a failure. First it was that "you can't buy anything for it," which was true until a pizza was sold for 10,000 bitcoins in mid-2010.
Then it was "no store accepts it" -- which was true until a few months later when you could buy things like web hosting from tiny bitcoin-only companies. Then it became "no large company will ever accept it." That remained true for a while, but eventually Wordpress became the first large company to do so. Others like Newegg, Overstock, and even Microsoft followed soon after. "Nobody will ever pay with it" was another one, and that was shattered once those companies started posting bitcoin revenue which, despite being a tiny share of their overall revenue, showed that people were consistently spending their coins.
I'm not saying that grandma will be buying gas with bitcoin anytime soon (or ever) -- just that there is substance there: merchants accepting it, consumers spending it, and interesting things like purse.io that couldn't exist without it.
