But that is what happens. The issue with GPUs is that a) there are only a small number of companies that make them b) fab capacity has to be booked in advance, and c) they know it's a bubble, so they're not going to commit to buying a large amount of future fab capacity when it could pop at any time. So then they don't actually increase supply, and prices don't go down.
> Maybe increasing the supply only increases the supply of luxury condos, which if they are all consumed by wealthy individuals might push housing prices upwards etc.
Only in the sense that the average cost might increase because the average unit is now larger, not in the sense that the existing smaller units would cost more rather than less. After all, their occupants no longer have to outbid the wealthy individuals who have put their money into the new luxury units instead.
> Such activity could, similar to bitcoin, actually stimulate enough economic activity in an area itself to sustain upwards trajectory on pricing
The premise here is that if you make an area more attractive then more people may want to live there. But that's fine. Suppose building 10 units increases demand by 5 units. So if you need 10 more units, build 20 more units.
In some kind of hypothetical edge case or rare circumstance, building 10 units might increase demand by 11 units, but that is obviously not sustainable -- if you built 50 million units, there aren't 50 million people in the region to live in the city, so at some point it stops being true, if it even ever was.
> Markets are weird and inefficient in all kinds of exciting ways!
This isn't markets being weird. If prices are high then construction companies want that money, which they get by building new housing. Weirdness only occurs when regulations interfere with their natural market incentive.
