No it can't. Lightning has a huge UX problem to use without custodians and/or permission, with bad receiver privacy and lackluster amount privacy from larger nodes. And if you fix the UX problem with custodians or LSPs you lose any privacy benefits you had with it.

Black markets AKA free markets are highly adversarial environs and the proving grounds (Bitcoins origins). The only places that don't require permission for your transactions are outside white markets. Bitcoins entire value prop rests on that. That's why it's a huge fucking deal.
