not to mention people who are going through a divorce or whatever and don't want to give half of their btc to the ex. I can think of several legitimate ways that anonymous transactions apply in the real world.
Just because you might not want to give half of your assets to an ex, it doesn't hold true that you are entitled to withhold half of your assets from them. Do you know what happens to people who refuse to cooperate with court orders? They get found 'in contempt of court', and liable to anything from a fine upwards to prison time, repeatedly, until they do cooperate.
The same goes for all the bleating about 'der gubmint' coming to 'take away' all that you possess by way of their grossly unfair system known as 'taxation'!!!1!1111111!!! Yes governments are predominantly inefficient bloated organisations that waste a large amount of the income collected from the people, but that does not entitle you to arbitrarily decide that you are going to refuse to pay taxes and, instead, will 'hide' all your monies in anonymous crypto. Did I explain what happens to people who refuse to cooperate with court orders?
If you hate your government and all they represent, do something about it by changing the system from within, not by fucking the rest of us over by your antics costing more expenditure (of tax monies received) and man-hours to deal with.
The US preponderance for paranoid and pot-stirring media pundits does it's people no favours when it comes to getting them to understand that 'The Government' is not the enemy. The enemy is the enemy.
