Hands down.
But I'd like to see approaches like "two weeks a month" rather than "three days a week". Start the month off with planning, brainstorming, collaboration, integration, then end it with heads-down focus.
I think it would also be interesting to see what ends up happening when cal hsr is finished. Now you can live in merced and could end up in sac, la, sf, san diego, anaheim, population and job centers all over the state really for a lot less hassle and cost of flying. Trains are generally more spacious and comfortable for getting some work done on the laptop as well, maybe you can bake the train commute into your working hours since you'd essentially be in an office that moves at 220mph around the state.
Now compare that to an office lease where you can get. At an avg density of 200 sqft/person[1], you'd need 10,000 sqft. You can get that for ~500K$/yr[2]. You use that for 10 times in a given year and you are breaking even.
