Fine, and what if those second / third layers are years and years down the road?
We have some potentially very potent catalysts around the corner which could multiply demand for Bitcoin fast, which ironically could cause (another) massive blow to how the public sees Bitcoin; Not just as an instrument for crime and terrorism, but an expensive one on-top.
Nice when five years down the road Lightning finally functions as intended, yet mainstream doesn't care anymore because that CBDC of them does the job just fine.
Maybe i'm seeing things too bleak, but waiting too long with certain steps could turn out as the wrong move.
