While I agree, it’s not impossible. MimbleWimble has proven itself on Litecoin and it was implemented (I believe) using a soft fork. So just as Ordinals was forced on the maxis, MimbleWimble can be forced on the maxis as a payment channel if the demand is there. Note, MimbleWimble isn’t as private as Monero, and the fact that it’s possible to know when something goes into and out of MimbleWimble may make you targeted as a “money launderer” makes it risky. But at least its a step forward.
