Not quite the same money. Employers willingly pay a big cost-of-living premium for face time. I doubled my salary by moving from Seattle to the bay area, which is to say they could save more than 50% (including office space) by hiring someone in the same time zone and a short plane ride away from meetings, yet they aren't even doing that. Founders don't have this opportunity cost (or rather, they've already accepted the opportunity cost of 100% of the market rate for their labor), so work while travelling makes a lot more sense for them.
