Is not so easy. A DNA chain is a physical object and information at the same time. If you copy it, you are copying an object that could be used to "make a copy of you", and allowing "random company or people" to pick this info opens the door to several problems. i.e. Imagine that somebody stole your sperm somehow and use it to make a child and blackmail you asking for money each month for 18 years because you are "the father", so pay me. Boris Becker suffered a similar case.

In the same way synthetic fragments of your DNA could be left in a crime scenery. It would be enough to clone only the handful of good parts able to trigger a rape test, and we have machines that could be feed with your public data and programmed to do this. No need to say that this could put you in a jail for the rest of your life, or worse.

You need to protect yourself from a lot of posible evil uses of your unique code, past and future.

No one is using the physical objects for their research. They sequenced it (at your request) and are only using the information for research...

This information can be easily used to regenerate partially the physical object.

Are you saying you wouldn't download a car?

Easily? Any proof that it had been done?
