People have been debating the blocksize for a very long time now and there doesn't seem to be any large desire to change it so while the ability to increase it exists changing anything that fundamental about bitcoin seems to be a non-starter and while that is true lightning is pointless as a solution for the masses.

Even if you increase the block size 100x though you're still not improving the numbers much since my very generous numbers ignore activity outside of lightning and assume a single on chain transaction for every user and a perfect network.
