I don't think you could. Let's say you found a house for $50K that meets your requirements. Heck let's say you bought a trailer for $20K and found some land for $10K. You'd still have $200K left (don't forget you had to pay $70K in taxes on it).
$200K could net you about $10,000 a year if you put it in super high rate tax free muni bonds.
Even with the hermit lifestyle and no taxes, you'd still have to pay for maintenance, property tax, food, and clothing once in a while. Remember, we're talking retirement, so you don't have any other income.
I don't think you could pull that off. Substance farming is work, not retirement. And like you said, without internet, you'd pretty much be relegated to desert paining.
That is $2000/month to live on. That will buy plenty of food, and clothing and leave something left over. It will not buy good health insurance, but you are poor enough to qualify for subsidies. I also selected a mild climate where you won't need much heating and cooling. Property taxes are cheap in rural areas (state selection matters). Maintenance is cheap, though you do need to do it yourself.
