In a normal market, I suppose speculation would help increase supply - by driving prices up, it would become more attractive to build. Of course if no building is possible, that won't work. Nevertheless, there has to be a ceiling to the prices. If no space for living is available, eventually the tech companies won't be able to grow further because they can't hire more people.
