Interesting. If we think of LN, we have that: not only ability to withdraw, but also ability to maintain currently held funds, passively, can be violated even without 51% attack but merely through censorship by miners, or even pure unavailability or pricing out through fees > available balance. Hence someone put it in some pithy statement that I can't remember along the lines of "in Lightning censorship resistance is a security requirement" (meh I can't remember exactly but you get it). But then is that overlapping with a 51% attack, or not? I always thought of the latter as specifically referring to attempts to "undo" payments, so changing inclusion and/or ordering of txs. I think I'm trying to say that, with this definition, even LN doesn't count as an L2, does it?
