If you see it from that perspective, yes. But the point is that server owners need to have an incentive to use it. If most of the domains don't have an SPF policy, anyway, and many of the remaining a softfail policy there's not much incentive for me as a server owner to check all mail. That's wasting a lot of dns lookups. On the other hand if a lot of domains use it I can reject a lot of spam from bots as a side-effect. That's a clear incentive to implement it.
