Money always coalesces to one but currency is always diverse. The multiple layer 2 solutions allow the money to adapt to its market demands. I think Lightning has a big headstart but I don't think currency ever stands alone. All that to say, just be prepared to adapt your mints to another layer 2 implementation when it comes along.

Anything you have in mind?
There are implementations of several with different trade offs. Liquid being a side-chain is interesting though 11/15 custodians need trust. There's something I have been tossing around that you could essentially create unlockable UTXOs as a sort of Layer one Treasury for a layer two token whose transference provides a nonce to unlock the underlying locked bitcoin. But, I am not a good enough cypherpunk to code it without having serious flaws. Though, I do believe it's possible, juwt not in my hands. This opens the door for minimum sized UTXOs to be established so the "I won't be able to spend my Bitcoin later" people can stop complaining. Also, with value appreciation, Those Minimum sized UTXOs allow for much more market expansion within a single treasury lock up. And anyone could make it without being a "custodian" (because once they spend the commensurate tokens they are divested from the treasury.
But that's all I have personally. I'm sure this can be flushed out more.
