You say that as if the users do not have full control over their Bitcoins and channels. They still do have 100% of their coins.
OMG..
lets address the last point first.
in LN YOU DO NOT have full control over your bitcoins.. LEARN MULTISIG
it requires signatures of more than one person. atleast learn that as a basic first lesson.
just because it is using multisignature features it doesn't mean you don't have full control over your funds. you still own the signed transaction that is required to "settle the real balance on the blockchain" so to speak if the other party didn't honor his end of the deal.
maybe you need to read the paper or use LN first at least then talk about it!
