All within the custodial safety of a node provider, just like a bank! The funny thing is that Bitcoin is fast and cheap on layer 1 already, but greed and number-go-up thinking,  as well as shit-talking and an irrational love of code that doesn't begin to resemble the bitcoin white paper have distracted the masses from a bitcoin that actually works. 
If you think one lightning transaction is all it takes, maybe you should try one BCH (or Monero!) transaction and you will ask yourself 'why am I wasting my time with Lightning'. 
Lightning was invented to solve the problems with bitcoin, that bitcoin was invented to solve for banking. Fast cheap transactions. How stupid is that?
