Most /24 seem to be marketed a little higher than that, so you’re really looking at ~$7500 USD for a minimum size prefix which you could advertise.
I do generally agree with your assertion this isn’t unaffordable, since the people who are most likely to care about owning their IP space instead of borrowing one from a provider like AWS most likely have other more significant costs like LIR fees, renting space/power/cooling for equipment, buying servers and network devices, etc etc.
