On chain was never intended for WW adoption and will the coming decades not be able to do so and I think it is also not needed.

In fact Satoshi himself realized and stated this.

Plenty of explanation available why it can't be done without losing key properties, and why it is not needed.

Lightning is perfect suitable for small transaction and so successful that even I as plep could do every transaction I would like to onchain within the next block if I'm willing to pay the 2-10 sats/b.

And that is just a first attempt for a second layer and just a second layer.

All shitcoins and their fan boys are just looking for non existing problems to sell their shit.
