You're right, it's a hack. Doesn't mean it's wrong and doesn't work though.
BTC stopped being practical for small payments when it got expensive. This is a way to make small, everyday payments cheap again. I'm not going to use LN to transfer large payments. "just DoS the watchtowers" is impracticle for a cup of coffee. Your second point is just plain false and there are many ways around those.
