But why doesn't this rule regulate it?
CRF Rulings by Term - Targets wrote:A target is an entity that an action is played out through. Enitities are only targets of an action if the action specifies those entities by number and type. Note that "the foo" counts as specifying one"foo."
"The site" means "one site." Not "all other copies" of a particular haven. Plus, there is nothing in the rules about targeting to suggest that targeting a site can target multiple sites (vs effects that don't target).
Also, this ruling on Greed seems like it would apply to the untapping situation discussed here by similar reasoning.

Hmm, hadn't thought about that. I guess you're right, it would only
affect B.
A similar ruling was given for River. Of course, these are hazards played on a site and not a resource targeting a site. But this is just a side topic to the CRF rules on targets.
