I think the rigidity of land ownership will be put to the test because of climate change.

I think for a lot of people, their deeded land is in eventually in terms of lat/long, and if the water swallows their land or their land falls in the sea, they're pretty much SOL. Depending on the rules of their locality, they may keep ownership of the land that's now underwater: it may effectively cease if underwater land is not subject to private ownership, or it may continue but not be of value because you may not be able to exclude other people from the land (or the waters above it) or develop it.

For some though, the deed may be defined in terms of the coastline, and then they're going to have an interesting legal battle. But this isn't without precedent; coastlines and waterways change and things defined against them adapt.

No country I am aware of uses lat/long for property deeds

That's just another name for war.

No one "owns" land, they just protect and area that they claim is theirs.

How much of other people's tax dollars do you expect to spend to safeguard the bad purchases of land (soon to be water) owners?

Rising sea levels aren't new, it's ancient. Buying coastal properties always carries risk.

Society at large should not have to keep bailing out people who make poor decisions like this.
