Lol I'm already seeing people say USDT transfers on Bitcoin are good because it will generate fees for miners, all because the mempool cleared for the first time in ages, like man chill out
Discussion
Mempool isn't a concern. If ETF's didn't happen then the mempool would but full and everyone complaining of high fees. Again.
Onchain + Other layers will provide L1 security.
Many L2s are in development. Stacks, Bob, Starkware, etc, etc.
It's good for Bitcoin.
Why do you believe it's good for Bitcoin?
