The hope of test-score driven funding is drying up due to every reasonable adult in the system collectively snubbing Musk and he throws a tantrum about it because "how do they even KNOW biology test scores are going to be bad!" while the students are jousting with the dismembered femurs of the bio lab skeleton in the background and in the wake of this all he's decided to triple-down on his "nuts to them who needs them!" approach because relying on test-driven funding means he can't run a Cool No-Rule School so he chooses to ignore the part where 90% of the funding is procured this way and every single second he spends on his ass in that principal's seat is burning a hole through his pocket and instead he settles on his most genius possible idea: selling fake ID's.
And when someone asks "Well what about the students with real IDs already?" he decides those people have to pay to keep them and to the questions of "Well what about those unsavory people constantly trying to break into the school" Musk assures them that those people simply wouldn't be bothered to pay the money for the fake IDs that run for a whopping $8 a month.
Meanwhile in real time a sizeable portion of students who've hated his guts since Day One have all collectively purchased Musk's own student ID and are parading around in full impersonation of him while he scrambles to draft a "No bullying the principal!" rule which he keeps himself hunched over concealing because no one can know he wrote this rule or else their illusion of how cool he is will shatter. And then the police get involved and inform him he can't be selling fake IDs like this and Musk rolls back the program like this was all just a social experiment (for now, until he brings it back).
And this all takes place in the course of about 7 days during which Musk has racked up an additional $20million in debt from loan interest alone.
