The language you are using here - specifically the word "suffer" - is indicative of a certain type of (generally Western) mindset where productivity plays a big role in a person's happiness and satisfaction.
I went on a two week vacation to my home country of Turkey back in July. For the first few days, it felt really odd to not work. I would wake up in the morning, have breakfast, fire up my laptop on the patio of my parents' house, and then... stare at the screen. After screwing around on HN and other sites, I would realize that it was 2pm and that I had "wasted" half my day. And I would feel bad about that.
After a few days though I realized how absolutely ridiculous that mindset was. I was on vacation and I was not supposed to be producing anything. I was supposed to be relaxing. It was like flipping a switch - I made a paradigm shift and spent the rest of my vacation "doing nothing." It felt great!
If I ever find myself in the author's situation where I have sufficient savings and am sitting on a beach in Thailand, instead of trying to continue working and getting stuff done, I'll just check out mentally and enjoy life.
If you go for holidays, you can tuck away your laptop and just rest, but if you plan a year long work&life scenario where you work remotely from another country, your productivity matters.
