On the face of it the implications of everyone having access to regularly-updated high-res satellite images of virtually every square inch of the planet (minus sensitive areas and uninhabited wilderness) are extremely interesting, although I doubt that we would see the wholesale exploitation that you envisage.
We're not permitted access to the full-blown, military-strength imagery, and probably never will be. We don't even see the latest images - most of the stuff on Google earth was captured yonks ago. My driveway contains a car I part-exchanged over a year ago, for instance.
As far as legal rights go, in your nude-sunbather role you don't have any - you haven't been specifically targeted as the object of the image, and you don't have the right to say "I don't want to be included in any satellite images" - any more than you can ask not to be photographed by a CCTV security camera. It's totally impossible for anyone to exclude a named individual from such imaging technologies, so we all have to put up with it.
Publication of the images is also something you have no control over. The person/organisation who/which captured the image has copyright, and may publish at will, provided there's no infringement of decency laws. An aircraft may fly over your house on a summer's day and photograph you sunbathing on your lawn - there's nothing you can do about it, unless you can demonstrate that a specific and deliberate intrusion on your privacy was intended by the photographer. Just before the end of the 20th century a private company photographed about 85% of the UK from the air, as part of a project to produce what was named "The Millennium map". The resulting images are so detailed that it's possible to see a 25cm object on the ground. Lots of the images must show us enjoying the countryside in the fine summer weather, and some of them will undoubtedly show some of us enjoying each other in the countryside, if you follow my meaning. These images won't ever be published of course.
The question of people taking advantage of satellite imaging for commercial purposes is an interesting one, but I doubt it would be that easy - in most developed countries the relevant authorities would be onto that kind of thing pretty quickly, and advertisements would be removed - the UK planning authorities would soon ensure that we added the necessary clause to the planning laws.
