I have no idea where you get this concept about the first 32,570 blocks. I reckon you don't know what you're talking about. There isn't even a concept of blocks in the Ripple ledger, that's a blockchain thing. The Ripple ledger stores a history of transactions, not blocks. See https://bitcoin.stackexchange.com/questions/58139/difference-between-bitcoin-blockchain-and-ripple-ledger
I realise lots of crypto enthusiasts hate Ripple and XRP because they're working WITH the banks, not against them, but let's get real here. Banking is not going away. Central banks are not going away. So why not try to improve banking systems rather than disrupt them?
Also to your point, ripple does not improve current banking systems, considering they are already able to replicate exactly what ripple does, why would any central bank with all the power in the world, ever use some shit coin? When they can just make their own USD coin, and use their own ledgers, they will NEVER give up control of the processing system. Buy bitcoin instead. Good luck!
