We can build up though. I might be worth 4 feet of shoreline, but my 40 foot sea view apartment is in a 50 floor apartment building, which leaves a lot of the shoreline unpopulated.
That assumes everyone wants shore view. With young kids I prefer my house to be far away from places weak/non swimmers can drawn. I know many other reasons why someone would choose to not live somewhere far from the sea if they get a choice.

That rules out whole countries. And misses all the fun of having water nearby. The chances of that happening are so vanishingly small that it probably is a bad guide as to where you want your kids to grow up.
~1000 American kids die a year from drowning - the rate has went down since pool fences became common. I'm not sure it's quite "vanishingly rare", though of course it's not common.
