Sure, it's called "property" and "contracts".

But these aren’t about the government allocating stuff.

Absolutely they are.

allocate: distribute according to a plan or set apart for a special purpose

Yep, when the government makes a plan like "5 hotdogs per person per week" that's allocation, and when the government makes a plan like "each 100x100 meter plot to the highest bidder" that's allocation, and when the government makes a plan like "special rights to the creator or their nominee until 70 years after they are dead" that's allocation too.
