If one uses a good source of entropy (e.g. dice rolls) then one will not "get screwed."

It's not for everybody, for sure.
How many users were told to verify the source code to make sure it was using good entropy? How many would actually do that even if told? Obviously not even the most hardline bitcoiners were looking at it.

Yes, the new cope I've seen is that you should've been using casino-grade dice[1] to make sure your entropy is good LOL. Mass adoption soon, I'm sure.
