All things being equal, I agree: The larger the potential cloud, the
higher the degree of anonymity. Certainly, restricting the node pool
isn't something that should be done unnecessarily.
However, in a totalitarian situation, it's wise to make the trade-off of
"shallowing" the node pool, to gain the much larger benefit of greatly
reducing the chance of the government censoring the exit - or worse,
breaking your anonymity.
