Because nobody makes 24V power supplies for computers, they'd have to convince the whole industry to agree on new PSU standards.

We already have a new PSU standard, it's called ATX12VO and drops all lower voltages (5V, 3.3V), keeping only 12V. AFAIK, it's not seen wide adoption.

It's also of no use for the problem at hand, PCIe already uses 12V but that's way too low for the amount of power GPUs want.

It's not great. Dropping 5V makes power routing more complicated and needs big conversion blocks outside the PSU.

I would say it makes sense if you want to cut the PSU entirely, for racks of servers fed DC, but in that case it looks like 48V wins.

24VDC is the most common supply for industrial electronics like PLCs, sensors etc. It is used in almost every type of industrial automation systems. 48VDC is also not uncommon for bigger power supplies, servos, etc.
