You've made a lot of claims on this post, but can you cite a source behind your statement of "This is the first vaccine ever where you can die 13 days after a vaccine, and be classified unvaccinated."? It also makes sense, since you've taken a vaccine, but you have not developed the expected antibodies until ~14 days.
I am moving to Spain in April and will be working remotely for the company I started contracting with back in August 2018. I did a ton of research and prepared a pitch deck and presented to my manager, who then advocated for me and moved it up the line to get approval from the department.
Some key points:
1. The company already allows a very flexible work from home schedule.
2. Although primarily focused around my region, there are a couple team members spread across the world. So it's not unprecedented.
3. The person whose role I took over (contract as well) moved to another country but then quit when they had trouble adapting to the culture (there was an eight hour time difference). So I had some possible baggage to work around.
4. I tested my ability to work off-hours and remotely with a two-week long trip to another city living with a friend and performed swimmingly.
5. You must convince them that, other than your physical presence, they will not notice any difference in quality of work, availability, or communication. Being that Spain has long working days anyway, the transition from my time (-7 GMT) to Spain (+1 GMT) will actually work out quite well from a working hours perspective.
I'm only 30, but I feel the same way. I've just never been interested in keeping up with the latest tech, I just like to get things done with the tools that work. PHP, JQuery and WordPress still work. I'm a generalist as well and have held positions or have done a fair amount of work in most areas of marketing in my 9 years in the industry.
I think your idea of teaching and doing corporate training is the right direction. You could then take your lectures and record those and build courses on those. That's how you create that content-momentum and spend less time building, thereby improving your ROI.
I've landed several jobs in that range without meeting someone in person. But it requires a certain amount of salesmanship and establishing proper scope.
