I would imagine that there are 'weaker' versions of the Malthusian catastrophe argument. For example, in most of the western world, population growth is negative (and is low enough to present significant problems). US, for example, sustains its population through immigration, as the locals aren't having enough children. Similar story for recently developed/developing countries like China and India where the population growth rate has dropped significantly.

What if the resource in question isn't food, but something like cost of housing?
