How did you conclude that i forget what block size is? I literally mentioned that in my previous post , but ya anyway, blocks have been capped at 4MB long before taproot, you could construct a block that large without taproot, it would just have to be a weird combination of transactions, but ya again, not sure what is the point of bringing this up.
I'm saying 4 MB is already pretty big. If you want bigger, go to BCH or BSV. Ultimately, the point is, even bigger blocks isn't a good solution. It's an easy solution but will eventually cause problems as we can already see with BSV.
BSV is poor example of big block size. It's doomed to failed since it's associated with faketoshi, don't care about cost/difficulty of running full node[1] where many decide to drop support[2] and even implement
stealing mechanism[4].
