Your word in satoshis ear :)

On chain fees are a problem, 1mb block sizes in 2024 as well, still missing privacy is the biggest problem to me. 

I like your approach, we shall build pipes between different technologies. 

Still we need to see that  the foundation for future payment rails  is being built right now.  If we accept to scale through custodians ( and Liquid is also a custodian, they take your BTC, they give you their L Token ) , then we lose the properties which made Bitcoin revolutionary far before we reach any mass adoption. 

The more people get onboarded and use a custodial technology, the harder it will be to change it later on. And the easier it is to force KYC. The problem is similar with custodial Lightning.

BTC used through custodians with a transparent chain can easily become the CBDC everybody is afraid of.
