Which also means you don't have a way of preventing all your movements from being followed, much of your health information being public knowledge, etc. > What is the alternative? Outlaw DNA sequencing? Only allow it if you know the owner? Even if it's on my property? The alternative is to establish rules and restrictions for circumstances for when DNA sequencing can be done... In fact, we already have some rules about that. You might think legal restrictions are ridiculous or impractical, but are they any more ridiculous or impractical than say copyright protections in an era when the copying & distribution of data is so frictionless and legitimately necessary? > Then how would you know every other place the person went that day? So many different ways... Tracking their DNA trail. Having a drone follow them as they move. Hacking their phone over bluetooth (hey, it's just emitting low power radio signals, are you going to ban that? ;-). Touching them with some radioactive tracer and then following its trail. Tracking radio transmissions from their phone. Planting a GPS tracker on them. Running a retargeting ad campaign and collecting the logs. Track their mass & its movements by analyzing how it alters the flow of neutrinos. :-)
