Who are you talking to? Who said anything about any of this? If you are
talking to me, please don't imply that I don't already know these things.

For a given fee amount, LN transactions are worse than on-chain
transactions. So people would only use LN if they preferred cheaper txns.

If you want fees to go up, either decrease supply (lower the blocksize
limit) or increase demand (a popular Bitcoin). There's no need to do
anything roundabout.
