They created Banks and they support them in their exploitive behaviour. <Giving them Bailouts when they fail>
In any way, Bitcoin cannot be traced if you use it in the correct way, so why would they worry about "evidence" if Bitcoin hides their evidence?
The power of corruption is when you can do this without being caught and they are getting caught regularly with their hands in the money bags.
If they add their own mixer services for these transactions, then the tx's will never be traced.
every day that you go to work or school,... why don't you use a tank as your transfer vehicle? it is much safer and can protect you from accidents. you don't use it because there is an easier way. you fasten your seatbelt and go within speed limit and you will be safe enough.
in your scenario you are saying the corrupt government is already hiding their tracks, they already have banks to bail them out, print money, have full control,... and dozens of other benefits. then you say they should give it all up for a
traceable and decentralized currency that they have no control over!. no matter what you think bitcoin is not anonymous even with using a mixer. and they will be caught even more if they use something like bitcoin.
if you said Monero or any anon coin like that then you could have an argument although I'd still say that disadvantages are still more.
