The Lightning Network is not bitcoin. The people who are fighting against block size increase are the same people pushing segwit. While there is nothing inherently wrong with segwit and the Lightning Network, they are ignoring the most important improvement to Bitcoin itself, which would be a pure block size increase.
The block size increase with segwit is marginal and a side effect. It's a complicated feature that is meant for purposes other than block size increase. Don't obfuscate the issue. I'm talking about a simple tweaking of a parameter to increase block size.
It's not marginal. According to the mix of current transactions on the bitcoin network, SegWit gives us an effective block size of 2.1MB. Over 2 times more transactions compared to today, which is more than what Bitcoin Classic was pushing for until not too long ago.

A "simple" block-size increase requires an hard-fork, which is anything but simple. Hardforks requires a network-wide coordinated upgrade where everyone updates on the same time, at the risk of a currency split and old nodes being open to attacks if not everyone upgrades in time. Hardforks are highly risky and very very slow to deploy safely.
I recently presented some slides on this topic, the relevant part starts here:
