Risk pooling is fundamental to insurance, but not all pools are the same.
The observation is that if you aren't able to discriminate at all or subdivide the pools, the only response is to up the average rate to cover the aggregate risk as best you can estimate it. This gets tricky if your ability to change rates is constrained, also.
These things are always in fundamental tension, and also in tension with privacy. It's not an easy problem.
