Lightning tx are trustless. They are not some idiotic trusted 3rd party solution like Dash's Masternodes.
Lol
If you really believe this than every other alt is trustless in nearly same manner.
-> Go and use them.
Think:
1. How much energy goes into making bitcoin that trustless it is?
2. How much do you need for LN ?
3. How much risk is introduced by any interface (complexity layer) like a pegging?
Pls go and read physics or Shannon about entropy and order -> security.
On-chain scaling is the most secure thing one could do (here you have the biggest hardware + energy investors = miners behind) and we need this first or at least parallel to all the other triggy (less trustless! - blockstream cash cows) scalings on top.
