Geez,
feels like I am teaching kindergarden.

LN is waiting on segwit, no segwit and odds are LN will not work as promised.

IF LN is working an unlimited number of transaction fees will then be processed offline.
BTC onchain miners will not receive fees for the BTC that LN has locked in place.
(LN secret goal is to LOCK all BTC in place and only have Offchain Transactions).
Once they have starved the onchain miners of enough revenue, they go bankrupt, LN operations will start a small asics farm to process their transactions.
Since LN makes all of their money offchain with no competition, they can run some asics to keep the ONCHAIN running at a deficient, therefore making them the only one that can afford to be BTC miners. 

In simple terms for you.
LN makes Money OFFCHAIN, cause BTC miners to Lose Money, LN completely takes over BTC by making ONCHAIN mining unprofitable for everyone. 

Now go play with your crayons.
