What about the increases in cars and foot traffic this creates, and how will increases to road congestion and transport services be mitigated? How will electric, sewer and water services handle this increases in utilization? There seems to be a multitude of factors at play in this.
Cars are bad. Walk, bike and take public transport --- aka learn from the large cities that already exist.
If we presume everyone drives, then all the de-zoning and other measures will never succeed, and e.g. SF is already at max density. If we believe we can make car usage go down, our current streets will be good enough for 10x growth.
