It comes down to a simple concept. You change with progress or you get left behind.

Even when progress is, in your view, undesirable... our world isn't a private place anymore... our expectations of privacy will seem silly to future generations... its jus how things work. Right or wrong are abstract concepts, and the marching of time pays no attention to them.

Only the truly privileged feel comfortable without privacy. Only once there is no such thing as an outcast, an undesirable, a freak, or a nerd, can a world without privacy be livable.

That assumes your vision is accurate, and that we have no control over our futures. Do only large computer industry companies get to decide the future?

When has the law ever been able to prevent the use of technology?

If we just assumed that whatever could be done (with technology or otherwise) should be accepted, what would the point of laws be in the first place?

People have expectations that the FDA will ensure the safety and efficacy of their medicines. Consequently, there are medications that I can't have in the US because of the law.

People have expectations of a level of safety on the highways. The technology under the hood of my car allows me to reach speeds of at least 100, and the law effectively prevents me from using it.

There are many ways in which people have expectations that technology could subvert. Automatically changing our expectations to allow for any technologically possible breach of those expectations isn't currently the way we do things.
