So if my key is 255 bits long, then don't I need to do the 255 2^255 hops anyway to actually decrypt something? And in running 2^255 hops, wouldn't I have also cracked the key if it was any number less than that?

So, there's a reasonable upper bound for the key length? Does that mean 256 bits aren't reasonable, and wouldn't this reasonable upper bound be more brute forceable?
