Never say "never." It's easy to imagine a future where interplanetary travel is routine, and habitable places are common (either due to the human race getting lucky in terms of there being an abundance of vacant Earth-like planets within easy range of future space drives, or due to the human race being diligent in the development of technology to live on hostile worlds or asteroids).
In such a future, I could readily imagine the human race expanding geometrically -- such expansion would end when we reached the edge of the galaxy, but that would still give tens of thousands of years of unlimited geometric expansion, assuming our ships are self-sufficient and can penetrate any within-galaxy area void of habitable planets, and also assuming our space drives won't allow faster-than-light travel (I think the galaxy is ~100,000 light years in diameter).
Should we count on things turning out that way? It seems irresponsible to assume so at this point. But it also seems like we shouldn't discount this scenario entirely, either -- and discounting this possibility is exactly what you're doing when you say "a type of moores law with land will never happen."
