Societies often place limits on individual freedoms.
Google is telling you to buy their particular brand of fence (which has inextricably an insane markup). And they disallow it for pool shapes they dont like and you dont have an appeals process for it.
So if you're a 3 year old child that wanders into a neighbor's yard and drowns, it's on you?
We know young children wander where they're not supposed to go, despite their parents' best efforts to supervise them.
So we do our best to legislate safety regulations when they can be low cost and high reward, like preventing children from falling into pools and drowning. We can't do everything, but when it comes to pool fencing the benefits seem to obviously and greatly outweigh the harms.
