DNA checks for accountability? How is this any different than simply requiring a password?
I mean really really think about it...in theory, passwords work perfectly....I create my password and only I know it...so, when I enter my password, there is no doubt that it's me....
Of course, in practice this system isn't perfect....people can steal passwords, hack them, tell them to someone else, etc...
What does DNA do to solve this? Nothing other than raise the threshold of difficulty to "hack"...sure, at first it would be really difficult to pull off illegitimately...but people's DNA is now going to have to be stored somewhere, and it's going to be just as vulnerable to infiltration as stored passwords....a few months, and someone is going to have a way to mimic someone else's DNA and pretend to be them...
Any society that can afford to implement "DNA checking" on every digital device and have it work accurately and quickly is also a society where certain people will be capable of "faking" or synthesizing DNA...
I'll acknowledge that DNA is harder to "crack" than a mere password...but in the end it doesn't end piracy to guarantee accountability...
Criminals carry swords, the police carry shields...police carry shields, the criminals carry guns...the criminals carry guns, the police wear bullet proof vests...the police wear bullet proof vests, the criminals use armor-piercing rounds...
It is a never ending process...doesn't mean you should just give up, but there comes a point where you have to stop and think if maybe your methods are too costly or too invasive (and DNA is both of those)...
