Monero is anonymous.  I do not know that much about Tornado but I presume it is less private and anonymous than Monero.  It is not YET banned however.  Why would Bitcoin be?

Developers of Monero were not forced to break the anonymous part.  Even if they were, we can move on from Monero to another fork that is not compromised.  But way before it actually gets compromised, audits are done by people who are skilled at coding and are also scared of their government spying on them.  They would find out about the gap in anonymity and action would immediately be taken.

It is not that simple.

Cool.  I have some United States Dollars and I can hide SO much fraud with it!  Is it a problem however?  Why would you have a problem with the United States Dollar, are you a terrorist or what?

Tools for hiding fraud transactions are all around us.  It does not mean they should be banned particularly considering there is no actual proof that a large chunk of the Monero, Tornado Cash, Mixers or any other tools have been used for fraud.  And by large chunk I do not mean one person moving millions in fraud versus the rest moving 'clean' hundreds.  I mean a large chunk of the PEOPLE using it.

Say Bitcoin is actually banned due to a handful of people using it illegally.  While Bitcoin is gone, fraud is still not.  In fact, it is alive and very well.  How many steps is the ban of privacy away from us then?  If they ban Bitcoin because some fraud exists in its ecosystem, why would they not oblige us to give up all privacy so they can find ALL the fraudsters?
