If you do not live in a dictatorship you have no right to comment on the usefulness of a privacy preserving tool. Maybe you do not see its value, but others in different situations than yours might need it.

So you want oppressed people to use the Chinese Yuan or Russian Rubel and Argentinian Pesos as their Currency (super unstable in value due to inflation, highly surveiled) rather than giving them choice to use something like Monero to transact in privacy?
