choice to have a pool without a fence is highly unlikely to cause me a problem without my input. If I know you have a pool without a fence, I can choose not to come to your house.
As for the "attractive nuisance" aspect of unsupervised children wandering into a neighbor's pool, I have control over whether I buy a house near an unsecured pool. And if my neighbor puts in a pool without a fence in an area where this is regulated by statue, I absolutely would be calling the city.
