Legit question, how do you work stably enough to have a good income to support this? Personally I find living a "regular" life and maintaining a 9-5 job is hard enough in terms of time management and logistics. And that's with the ease of not having to think about where my next accommodation, next meal, next shower will be.
Do you find yourself more time pressured? More stressed? Spending more on conveniences to make life easier?
In my case I simply refuse jobs that don't let me work when I want to. Daily standup? Absolutely no way. Weekly standup? Only as long as I can skip it on the regular.
I'm extremely productive and I'll work weekends, but if on a Tuesday at 11am I feel like going on a trip, I absolutely will and you can't stop me.
Honestly, when I was doing it, I didn't really find any of that difficult. The biggest pressure was from other people who I met while traveling to go out and party or do fun activities while I preferred working. I used time zones to my advantage when I was in Europe and Africa, so I'd have a nice relaxing morning, have a good breakfast, and then work in the mid-day through the evening, go to bed and do it again, and my weekends were still my weekends to do whatever I chose. When I was in South America I just worked normal east coast hours because most of the continent is on EST time zone or similar. It really wasn't as big a deal as you might imagine.
It's not like I was homeless, I would know I wanted to spend a month or thereabouts in a city and I'd get an AirBnB or otherwise arrange accommodations, I'd pay for a coworking space to have a good place to work with stable internet connectivity (this actually was one of the most difficult things in some parts of the world, back then), and I'd eat like the locals either cooking at the AirBnB or going to local restaurants/cafes.
I don't think being nomadic has to mean living like a hobo, those are not necessarily the same things. I never stayed anywhere that didn't have basic indoor plumbing at least, although a few times I'd have to hand wash clothes in a sink and hang them to dry outside the window, which was kind of a bummer but not a world-ender.
Overall, my productivity didn't suffer at all, and I didn't find it stressful from the things you mentioned with even a modicum of planning ahead. In fact, being able to explore different parts of the world and head out when I felt satisfied or got bored, meant that I always had some sort of moment for inspiration that helped to fuel both my curiosity and my work.
