Why should taxpayers subsidize unsustainable prices for the restaurants/shops/services?

If it's just left alone, the market will react to this. If a 1BR apt costs $2500/mo, then the price of a sandwich might go to $25 to be able to pay that sandwich-makers $75k/yr wage. And if SFers don't like paying $25 for a sandwich then they can vote for more density.

Nah, there are much more viable market solutions. There will be 4 sandwich makers sharing that apartment, or they will commute for hours, or the sandwiches will be made somewhere else and shipped in, or the sandwich shop will make you build your own sandwich, or it will understaff and you'll have to wait 30 minutes for your sandwich...
