Yes a rugged individual would have to be incredibly wealthy to do it!

But maybe the governments will make one and maintain it with taxes as an infrastructure service, like roads, giving everyone expanded powers of cognition, memory, and expertise, and raising the consciousnesses of humanity to new heights. Probably in USA it wouldn't happen if we judge ourselves only in zero sum relation to others - helping everyone would be a wash and only waste our money!

Some governments probably alread do and use it against so-called terrorists or enemies of the people…
