No place is wonderful enough to pay billions of dollars in extra taxes just to live there. If you are a top engineer making $500K/yr, you're only paying ~$65K/yr in CA taxes, and you wouldn't make anywhere close to $500K in other cities. So the decision to live in CA makes perfect financial sense in that scenario. But in the case of a billionaire founder, it simply doesn't make any sense to sell shares while living as a California resident. You're essentially volunteering to pay a ~65% increase in total capital gains taxes over what they would be in a tax-free state.
If Mark has to stay 183 nights in NV (or stay in NV more nights than anywhere else), that might be more of a personal burden and inconvenience than paying CA tax. And if it harms his ability to lead his company, it might ultimately be more expensive as well...
If he wants to give $1 billion in cash away, there are alot better uses than to give it to state government bureaucrats. For example, he could have moved to Nevada, saved the $1 billion, and taken 50,000 homeless people off the streets for a year for that much money (which, by the way is ~10% of the entire homeless population in the United States - imagine the positive social impact of doing such a thing).
The point is that federal taxes are inescapable, while state taxes are not. It makes no financial sense for someone with nine or ten figure tax liabilities to be living in high tax states.

They'd have to move the company HQ to Reno/Tahoe to avoid the taxes.
I'm sure that Zuckerberg et al have brilliant tax accountants, but this is one thing that has never made sense to me. Volunteering to pay an extra 13% simply for the privilege of living in Northern California seems insane to me. Any of these guys could move a few hours down the road to Tahoe or Reno and save themselves billions of dollars in state taxes, even if they left the company headquarters in CA.
I'd also like to see Pricenomics do a study measuring the market cap impact of California's high corporate income tax rates on major publicly traded Silicon Valley companies. I'm guessing investors would be sickened by the results.
