I think the "risks" of disturbing a grave site are greater than any "rewards" for doing it.

A home in which someone died can be used again by another person after proper cleaning and what not. Wrecks on the side of the road are usually removed because they are a danger to other motorists.

In the case of Earhart's plane the air frame and navigation systems are 75ish years out of date so it's not like there is a pressing need to solve a potential safety issue. IMO there is nothing of value to be gained besides "solving the mystery" and perhaps gathering a few personal artifacts that could be displayed in a museum or returned to the families.

And nothing of practical consequence is learned from exploring the tombs in Egypt. We might be able to decipher some tidbits about everyday life thousands of years ago, but one would be hard-pressed to explain what tangible benefits it offers, beyond "well, it's a part of our heritage / it's cool to know". Just like many other human activities, it's glorified idle curiosity.
