Second layers are a scam, they're creating horizontal networks with massive risk as you rehypothecate assets that aren't native to it and you're not porting the history over either so you're effectively just using a centralised service run by a small amount of people who have even more control over that system
In addition, they all have their own native token, which allows them to remain in control in perpetuity like ETH the chain they're all based on since all of them are proof of stake and if you have a premine no one can out strip your sucking up of the inflation
