2- Segwit+L2 is a scaling solution as it makes it possible to handle several times more tx's for the same blocksize.
Proportional increases are not scaling. You seem to not have read my link where I explain what a mathematical definition of scaling is.
You also did not address my main points.
Also I edited my original post slightly. For example I pointed out that IoT may eventually require billions of transactions per second.
Really I dont have time for this right now. But I will be back at the right time. I would rather let Core dig a deeper hole for themselves first. Why interrupt the enemy when they are in the process of destroying themselves.
You seem to be full of shit, anunymint and trying to lord over your supposed technical/mathematical skills to spread doom and gloom FUD.
Of course, bitcoin (through segwit, lightning network, and other combination of off chain and on chain solutions) is not going to process billions of transactions per second today, because it is not needed today. You don't build an aircraft carrier sized boat if you only need to carry one passenger, but as the needs get bigger the boat gets bigger and the functionalitiy gets bigger. the various combinations of bitcoin, segwit and lightning network is facilitating bitcoin's growth in that direction and they are secure, but if more is needed later down the road, then those systems will evolve with need(s) and increased usage. Scaling allows for building up to future levels without the necessary waste and burdens of overcapacity that is not currently needed.
You try to assert that there are fundamental foundational or building on top of bitcoin flaws, but you are largely throwing out non-backed up nonsense rather than really working with both pluses and minuses, you exaggerate and harp on supposed negatives that ends up in a bunch of bullshit speculation about scenarios that have about a snowballs chance in hell to play out as you hypothesize.
