Transaction fees can be thought of as an auction protocol where users bid on the unit cost for a block’s compute capacity. As in a first-price auction, people pays the highest unit cost for block capacity to get their transactions mined sooner.
 
I realized that auctioning requires a license in many jurisdictions. Why haven't governments attacked Bitcoin using this weapon? They could go after miners or full nodes (or even core devs).

An auctioning mechanism is even more obvious in other blockchains when the users having the highest stake are selected to provide a certain service.

In particular, Blind Merge Mining, which has been proposed as a BIP, is another auctioning system to be embedded into Bitcoin.

Forgive me if my question is naive.
