What I think he means is that there is no in-protocol mechanism for slashing a censoring validator. But you can reach a social consensus (i.e. outside the protocol) and decide to slash the censors. At that point there would be effectively two different chains, the censored one and an uncensored one. The worth of each chain would be decided by market dynamics.
