This is a very interesting argument . I think it's worth noting that you can calculate an estimate of the externalities and remove that from the profit to achieve a more balanced justification. Though unfortunately, unless you counted the loss of culture as an externality then you could still trivially justify the removal of land from those less productive/ technologically advanced than you. Furthermore, even though I'm not personally supportive of the removal of land at the individual's loss I do have to ask if the removal could account for a net gain overall; improving many people's lives. Perhaps profit isn't the best measure of improvement to the collective but it is at least indicative.
