"People said, well, you know, the problem is these things [Lightning addresses] look like email addresses - what if you accidentally send bitcoin to an email address or something?"

Is that even possible? I didn't read the specs about LN addresses yet but I highly assume you can't send something to a non-existing LN address? To which node should it go? lol

This is the way

If emails look like a lightning address, they should act like one.
