Maybe the key isn't the future but the past, i.e. the time of Rambo. If I ate meat, like Rambo, I could just carry a hunting knife and get free rides through towns from police. I could go without the hostilities and pressure-washing, though; but maybe a shower and getting my laundry done would be a compromise; oh, and I'd take the haircut just because too much hair is annoying in the wind.
