I think lightning fixes a payment related problem we currently have with Bitcoin that monero is not able to address without new or old problems reoccurring.
BTW: I know nothing and I am here to learn.
Monero might be a great privacy tool but lacks the power to recreate a useable finance system due to its untraceable character.
Afaik Monero can not fight or fix the fiat system. It can only protect your personal freedom if you buy illegal things.
