I want someone to build a fully centralized L2. 

There's a bridge that lets you get in and out to ETH. But once you are in, its literally boxes on AWS running the EVM at full speed. You get near zero fees, infinite scalability and the ability to exit and "decentralize" your money, but you are trusting the operator while you are in.  

I think there are some use cases for crypto that would benefit from this

Technowatermelon. Elder Millenial. Building Farcaster.
