It's not, but semantic arguments are pointless. If you want to use "rent seeking" to mean something different from what it normally means, fine, I don't mind using different words.
> As soon as anybody owns any piece of land or capital, they are not doing anything to produce any value that is derived from it, they are simply collecting money for controlling a scarce resource. Those two factors of production can create ongoing value without any intervention from their owners, and you either support a persons right to own those resources, and collect some portion of the value they create, or you don't.
> Also, what's wrong with unearned capital? If I give somebody a hammer, do you have some sort of moral objection to them deriving income from the increased productivity that would create for them? Because I would suggest that the only thing that matters there is whether I had a legitimate ownership claim to the hammer in the first place.
Right; the point is that land and capital are very different. People can legitimately own hammers, which are the work of human hands (yes, access to the means of production could be a factor, but if we assume that production of hammers is now widespread then it's irrelevant). Claims of ownership of land (or radio spectrum, or so on), if you mean chattel ownership, can't ever be legitimate, because people can't make land, only seize it.
