You are right, the general statement is applicable to long range unblockable attacks, not unblockable move. Since they are combined in the above piece I didn't specify.

That said, I believe that valk is worth more than a knight in CEO cost(ofc it also has king teleport), so I'm not convinced by yours claim about that camel is worth less. Likely it's an analysis from a different chess variant. CEO pieces tend to have very localized movesets which makes long range unblockable type attacks more powerful than they would be in normal chess. Though (1,3)-leapers have extra movement problems since 1+3 is even/they can't get to all squares so it's hard to argue that it's that good. zebra sounds way better than knight to me in this game though.
