Yes, that’s exactly what the devs are doing with the lightning network. The devs are removing the miners incentive to mine through the implementation of the lightning network. What do you think the blocksize debate is about?
The whole economic model of Bitcoin is literally destroyed for the socialist oligarchy of lightning nodes to collect their ‘hidden fees’ off chain. It’s central banking all over kiddo.
Lightning is an extremely tiny portion of the total transaction volume. This is a funny narrative that you've constructed to shill your fork of an altcoin, and nobody believes you. Mining won't come to a stop due to lightning because for as long as you and I are alive there will always be a block reward. The last bitcoin won't be mined until 2140, so its not really a problem to be concerned about for the next 120 years.
