>why you and other commenters are so supportive of transaction tracking

because most people aren't a fan of tax evasion, black markets or crime. The same does in fact apply to cash which is why many jurisdictions heavily restrict large cash transactions and are in the process of reducing the usage of cash or circulation of large bills.

I think the NSA, FBI and CIA being able to do their job is a good thing because I'm not too keen on making the life of money launderers any easier.
