It’s worth noting that his minions are building a tool to block individual payments (eg: social security for a specific person) if they so choose:

Overnight, Wired reported that, contrary to published reports that DOGE operatives at the Treasury Department are limited to “read only” access to department payment systems, this is not true. A 25-year-old DOGE operative named Marko Elez in fact has admin privileges on these critical systems, which directly control and pay out roughly 95% of payments made by the U.S. government, including Social Security checks, tax refunds and virtually all contract payments. I can independently confirm these details based on conversations going back to the weekend. I can further report that Elez not only has full access to these systems, he has already made extensive changes to the code base for these critical payment system.

This would give him incredible power to punish people he doesn’t like, and we know that Musk has a LOT of those.
