[Marvel] Why haven't the Asgardians declared Eminent domain on the infinity stones?

Surely a bunch of fecking humans can't be the best ones to keep it?

As was previously said, having more than one Infinity Stone in a given place isn't especially smart.

First, Asgardians aren't invincible and Asgard isn't impregnable.  On the off chance they *did* fail to protect their home, any enemy that conquers them would still only have a single Infinity Stone to their name.  Further, Odin kept an Infinity Stone on Earth for one of two reasons; either humans were entirely too stupid and weak that nobody would honestly think that he'd seriously keep a Stone there (lending to security by trickery) or that humans had the potential to be some of the baddest motherfuckers in the galaxy (lending to security by humanity).  Either way, the Tesseract is secure.

What's more, Odin may well be aware that perhaps Asgard isn't *the* safest place in the universe.  Were it not for the Convergence and some truly shit luck, the Aether would never have been recovered, for example.
