Lots of interesting comments here.
My life is not unlike the woman you've described –although with a few differences... Have namechanged as this may be outing.
I left the UK at 26 and have worked remotely online ever since (11 years), hopping around the world. Part employed, part running my own business.
Spent time in around 14 different countries over the years by housesitting and doing work exchange (including the Caribbean, Amsterdam, South Africa, Copenhagen, Italy and Tokyo) and, counter to what many people expect, actually saved a lot of money that way. No rent to pay, no bills, lived in luxury homes, treehouses, sailboats, city centre apartments largely 'for free'. I saved the deposit on my house by living this lifestyle –no way I could have done it in the early years of my business if I were paying rent, bills, commuter costs etc. in the UK.
I did it both single and with a reasonably long-term partner who also worked remotely and travelled with me.
Now I have a 'home base' on a Greek island, and until the pandemic hit, I travelled just under 6 months of the year in total (mostly for tax reasons), coming back to 'base' when I needed and wanted to.
I've been with my DP for 5 years now, and we have separate homes. Fully committed, fully in love, but have chosen to have our own spaces between which we share our time.
I spent a lot of time thinking about whether or not I wanted kids and have decided it's almost certainly a 'no. DP is fine with that, and he has a wonderful daughter from a previous relationship who's one of the loveliest humans I know. I get to be in her life and contribute to her growing up without being her mother, and that feels just right for me right now.
And I also have very solid, very wonderful friendships in many places around the world, including my 'base' and also in the countries I've lived before. Many of them also live 'unconventional' lives but they've been there for me through thick and thin, and thanks to their 'unconventional' setups have been able to drop a lot and come to be with me at some of the hardest moments of my life – in a way that my more 'conventional' friends wouldn't necessarily have been able to even if I lived in the same town.
The constant travelling was lonely at times, which is partly why I set up a home base, but to PPs negating the value of this woman's friendships, 'unconventional' doesn't mean 'fair-weather' in the slightest.
None of my choices have meant that life hasn't still been 'life' –there have still been illnesses and breakups and challenging moments and times when I wondered what the flipping heck I was doing 
.
But if meeting this woman has made you want to be more intentional about your choices, even if that means going against the grain just a bit, more power to you. You get one shot at this 'life' thing, and if you're lucky enough to be able to play with it in whatever way feels right for you, by all means do so.
