"Oh, that is wicked. How does their subscription work when their demographic has no home address?"
Ah, patience young grasshopper.
Since you are embarking on a "homeless" existence for a while, perhaps I can provide some tips.
When I was in my late 40's and going through a divorce in the late 1990's, I decided to live a really simple life -- even though I had to pay alimony and child support. I knew I could do it, since I had done it in my early 20's. My house in Palm Springs was rented out and the tenants provided income for the mortgage.
I got a job which required 100% travel. Meaning each week I was at a client's location. My office was in Michigan and I worked throughout Arizona, California and sometimes other southwestern states. My company paid for hotel rooms during the week and I got a daily per diem to pay for food. So this meant I didn't really need to live anywhere, although most people would have lived in a house or apartment on weekends.
So I decided to live in my 8 foot tent trailer.
Note: This picture was taken around 2003, since it is connected to a 2003 Expedition.
I towed it to each city I worked in, usually living in a campground or BLM or USFS dispersed area during the week. If it was too far from my client to camp somewhere, I would stay in a hotel and just leave the camper in the hotel parking lot -- but this rarely happened. The only difficulty I had was when I submitted a campground receipt in lieu of a hotel receipt. But my boss was convinced I had taken too much LSD in my youth so he let it go through.
On weekends I would go backpacking or camping somewhere. All vacations and holidays entailed backpacking or camping too.
I quickly learned that you cannot live in the US without a mailing address, especially for banking and government ID's. So not wanting to be reliant on someone to use their address, I rented a private postal box in the Phoenix area, which was about the central point of my travels. If was away from Phoenix for a few weeks, I could just call the postal place and they would package up my mail and sent it General Delivery to somewhere I would be.
My pay was direct deposit. Even back then I could pay bills via Quicken and Bill Pay, so a paper check was a rare requirement.
All my possessions went into a storage unit in Arizona. My mechanics tools, whatever backpacking and camping gear not immediately needed, my stamp collection, vinyl records, books, and clothes not immediately needed. It was a pretty small storage unit and I was surprised that all my accumulated belongings of almost 50 years fit in it.
In the late 90's there was no broad band, the Internet was still in its infancy, and most companies used PROFS email. If you knew where to look, you could find pay phones with data ports. That is how I did my email each night -- on a 1200 baud pay phone. No coins were needed because my company email connection was an 800 number.
My home and business phone number was my cell phone. Back in those days cell phones were expensive, so I rarely used it. Most people in business relied on pagers and corporate dial-in voice mail systems, and that was my primary communication method along with PROFS.
On the rare occasion I had to fly to my Michigan office, I would just park my camper and truck at the airport.
And this is how I lived for two years. It was wonderful! And no one knew I lived nowhere. Probably couldn't have kept my job if the company knew. Even my family thought I lived somewhere.
But alas, I fell in love, got married, and the new wife required a real house to live in. I got the Palm Springs house from the divorce and moved back in it. And now I have "stuff." I like my stuff too.
It would be even easier to do today. But we still must have a physical mailing address, mainly because the government requires it for identification, income tax, social security, etc.
