Now he argues that wanting to validate every Bitcoin transaction is "irrational." In other words, he suggests we toss the entire full node security model into the trash bin.

You must improve your shilling game, theymos is paying you for this crap?That doesn't speak to whether widespread SPV use is particularly safe at this time.

So let's not deceptively use his words, please.
