Or, consider starting a company outside of San Francisco. Not just outside of SoMA, actually outside of San Francisco. (I know, I know, blasphemy.) Eventually the price of real estate and labor will be so high that the relative disadvantages of other locations will not matter.
Eventually we might consider that rent is just outright theft, we're not actually paying for value, landlords are parasites who suck surplus value from the economy, etc.
The value you are receiving is location.
If you do not care for location, then rent office space in Tennessee where you can pay less than 1/4 of SF prices.
