Are you confusing “can’t” and “can, but is fruitless” (pun intended)?

Like, if someone says to you “you can’t put nails in with a screwdriver”, are you going to say “You totally can. Just whack the nail with the handle. I don’t see the problem”.

Or, like, “You can’t eat crayons” do you respond “sure you can. chew it up and eat it. i don’t see the problem. it’s just like a cookie”
