We see it every day. Someone asks "Can I buy a _ _ _ _ with bitcoin?"
Then come the confident ignorant to boldly say things like "No you cant buy a house because..." "No cars can't be bought with bitcoin because..." " No way it's illegal to buy guns with bitcoin because...". in fact you can buy about anything that can be bought with cash or cards and more. Retail adoption is upon us and while you have to hunt much more to find items, they are there.
Let's test this!
Post an item that you want to buy or find an item someone else posted. I'm sure we'll find some things that can't currently be bought for bitcoin. But my guess is that most things can be found.
Here are examples of the items listed above:
