Funny how you skirted my comment about the artificial language trick, guess that was too unconventional for you?
12 random English words is still 12 English words. I don't trust it, but it seems like you are okay with it. So what's the big deal if I invented my own language and came up with 12 words?

And using the internet and bitcoins are apples and oranges. You don't have to know how flying works with the internet, you just have to learn how to fly.
With bitcoins, you have to learn how flying works to understand how to be as secure as you can be.
And no, people don't know much about technology, and look at the consequences: stolen passwords, phished passwords, cracked accounts, etc.
Bitcoin just seems another continuation of that, but with the opportunity to lose a lot more.
