So basically Bitcoin maximalist dream come true.
Not really. Bitcoin Cash is just a big block bloatchain. It doesn't do anything innovative. At least coins like Monero offer us something that Bitcoin can't (not yet at least). For some reason, though, there is this fixation on increased block size...
Bigger blocksizes are necessary for more onchain transanctions, these are necessary because offchain transactions have specific use and cannot replace onchain transanctions. Without bigger blocksizes, not much more people can use Bitcoin to even store value. Its fine if altcoins have smaller blockchain, but if Bitcoin has to be store of value capable of being used by anyone, it need bigger blocksizes, thus blockchain size.
