@vit05, let me comment in this manner, a story was told about some group of zoologist who where afraid about the size of a specific animal (the elephant) They find an averge elephant weight about
100 - 120 Kg (220 lb) approv. when compare to the size of a fully grown one's
Now, based on the figures, they decided to device a way to trick, that is by chaining the elephant when they are still young in order to be able to control them when they are fully grown. Today, we've seen the effect of this trick on the elephant. They still work very slowly as if, they are still chained to a big tree.
This is what is happening today in our society. we have been so brain-wash that nothing else mean's much to us.
We tend to enjoy thing's which tend to keep us in bondage. pay tax,transparency in currency..ecc.
Most people are more miserable today with the existence of more security measures compare to when there are less security measures.
In conclusion, govt. can also track the purchase of sophisticated weapon if, they want to, if, such payment was made through the use of virtual currency. They can do this by tracing the destination of the package in order identify the sender.
Thanks
