The lightning network does not fix bitcoins fungability.  It actually makes it even worse. Alby etc are all tied to email addresses etc The lack of fungability in bitcoin  will make it worthless in the coming years for anyone except the elite  who are beyond the law (in the same way fiat allows them avoid tax but the rest cannot) .  Every bitcoin maxamilist knows this by now, which means every one of them is a scammer trying to push up the price before cashing out.
