Unfortunately I don't have much time for YouTube videos, but looking at his upload list it seems it's one of the hillbilly BCH big blockers who still think it's a good idea to scale on-chain, just because it works on their un-used network and they resist development and evolution of the network. If he argues against LN because he thinks it's too hard to run on low-power hardware due to size constraints (I would get processing power, but storage? Really?) he is basically saying his own coin (that needs more space) is not decentraliseable because low-power device can't handle a lot of data. He is then actually arguing against the security of his own preferred coin (BCH it seems).

So without even watching it, from what you wrote and seeing the video thumbnails & titles, I'd say this guy is clueless.
