Thanks for your thoughts!  Agree BTC should always be the base layer but it will be interesting to see what is built on top.  I think it will exceed our current imagination.

If such sidechains, L2s or projects building on top of them need their own token or if those tokens have any value, is a different question. I guess that is up to the market to decide. But I am a proponent of keeping BTC the main asset on all layers across the stack

Tricky question. I don't know a lot about Stacks, only that there is some Boltz fork out there doing swaps between Stacks and lightning.

Bitcoin scripting is certainly very limited and I can imagine use cases for applications running on sidechains or L2s that allow developers to build more advanced applications. Like for example this one, which is allows you to borrow a stablecoin with BTC collateral on Liquid (it's in private beta right now): https://twitter.com/fuji_money/status/1574766200948768769?s=20&t=6vQxLEmQ6oZ9kY2rnJvQnw
