Lets just call it what it is. A truly autonomous system.

Anyone who thinks it is worth their dollars and efforts. Or do you mean 
in the future, when those might not (be perceived to) be high enough to 
keep the multitudes out?

The biggest problem with this equation is that it is weighing my cost 
versus everyone's else.

And the cost to everyone else for my single prefix addition is 
negligible. It needs to occur dozens of thousands of times annually to 
actually cost anybody anything at which point it costs a lot. Since I 
cant stop the other prefix additions, there is no reason nor benefit for 
me to stop adding my prefix either.

I dont stop driving my car either.
