The article mentions that other planets don't have continents, but isn't that an argument against this hypothesis? The same process of asteroid collisions would have happened there too.

It may be that all those with continents are small enough that they slip though the detection net. We should probably hold off on the comparisons until we are able to readily detect earth-sized planets around similarly-sized stars to ours. Then we can talk about whether our arrangement is or is not rare.
