That may be true, but a city needs more than just tech workers to function. The goal is balanced growth.

> Restrictions on housing supply hurts everyone who isn't a landowner.

Objectively false. Affordable housing requirements help lower income people.

> whatever tech elites are doing, they don't look like they're winning the battle to up supply on housing

You mean up the supply of market-rate housing. Most critics are not anti-growth, they just want more affordable housing.

And as for displacing workers from other industries who can't afford market rate, it's not us vs. them. The "industries" you're talking about are intertwined: tech, restaurants, cafes, schools, police, nursing, art, and so on. If a city doesn't grow in a balanced way and pushes all those other people out it could make it an undesirable place to live. Already we are seeing big increases in restaurant prices due to cost of living.
