Any unbounded goal in the vein of 'Maximize concentration of <thing X> in this area' has local scope but potentially unbounded expenditure necessary.

Also, as has been pointed out for general satisficing goals (which most naturally local-scale goals will be); acquiring more resources lets you do the thing more to maximize the chances that you have properly satisfied your goal. Even if the target is easy to hit, being increasingly certain that you've hit it can use arbitrary amounts of resource.
