High level, you're never going to be able to negotiate with folks at this level; they got there because of, very broadly speaking, the "dark triad" personality [4]. Therefore, you're only left with "higher authority" to keep them in check, such as government, law, etc.

(thoughts and opinions my own, as always; I am simply putting forth a thesis based on observations and data)
In any case, Musk can be pro-RTO for the same reason numerous other CEOs are: they have significant sums invested in commercial real estate, and don't want prices to enter a downward spiral.
Commercial offices and real estate in big cities is fucking expensive. Like $100/year per square foot for nice office space at the peak. Each employee probably requires a minimum of 100sqft average to account for offices, conference rooms, etc. 10k x 1000 = 10m/year per 1k employees.
Figure like 1m or 2m a month per 1000 employees after you factor in all the other maintenance and required stuff for an office that size.
I would be surprised if they are not sitting anywhere from 70-100m/year of real estate costs.
Maybe 30-60m/year if they didn’t build out office space for their employees hired during the pandemic or got fantastic lease terms (which if they did, they would probably be subletting at a profit).
If you want to break your lease, in this commercial real estate market, guess what? Tough shit. You can pay the lease in its entirety or sublet the space.
Either way, it pales in comparison to the $300m/qtr they're on the hook for for interest payments to banks that financed $13bn of the deal.

Like when he tried to not close the twitter deal, just because you don’t wanna pay doesn’t mean you can arbitrarily back out of a contract.
That's what happening with their loan payments, at a significantly higher scale than vendors they simply haven't paid, and are hoping to shake down for better terms.
