there is no convincing argument on how trump can LEGALLY prevent djt shares from tanking.
of course, he may risk doing something illegal before or after lockup and then contest in court for years.
a complete buyout does not appear to be impossible for whatever amount djt (or any public company) can negotiate, which may have no connection to fundamentals nor share price.

trump can delay notice on whether he is dumping shares via a (private) 105b-1 plan with a broker.
he can also have a vague plan to direct the broker, and\or risk outright violations there as well.
trump's cost basis is $0, any amount greater is personal profit.

once insider shares are unrestricted, trump can negotiate a non-recourse loan with a MAGA friendly bank. this only prevents his own shares from entering the market and tanking shares. other insiders have to find buyers for significant # shares and probably will accept even near-zero prices since it is unclear whether additional retail (most current likely holding losses) nor institutional block buyers really exist.
many paths to a 'no bid' scenarios, i.e. pennies shareprice listing.
