> Secondly, NomadCost != cost of living. NomadCost is based on short-term staying in a hostel, hotel or apartment in the center, working in a coworking space and having a basic meal three times a day. That's the average digital nomad's lifestyle. They move around every few months, so they can't rent long-term. So NomadCost will be way more expensive than cost of living for a resident.
I suggest you to let the user expand the NomadCost into the three things you mention: short term staying, coworking space, three meals a day? Why? I may be planning to work nomadly in Tokyo for example, and for me it would be cheaper than what you mention because I can stay with my in-laws (and possibly could use the office of some friend). On the other hand, I would pay the same amount as a normal nomad for the meals, so if I knew how much they cost I could more accurately forecast how much it would cost me to stay in Tokyo.
I'm intuitively guessing that there's more geographic variance in rent prices than in coworking or food. Everyone will have different ameliorating factors in different cities, like friends or in-laws, and I'd argue that splitting out the NomadCost creates more mental work for a visitor than is necessary for the purposes of comparing cities to one another.
I think you misunderstood the request (providing the option to drill down doesn't create more mental work), but I also disagree about "we all have friends and fam"... the typical digital nomad is NOT traveling to see family in friends; they're (for example) someone from SF traveling to SE Asia.
My own family & friends are split up all over the world (and my wife's parents live on the opposite of the world from mine, and we've lived in 3 different countries at one time or another but now are sort of in-between them), but it's still really unusual.
I'm pretty sure the calculations are assuming you don't have family/friends to host you.
