“Safe” comes down to your risk tolerance. Do you trust having all your transactions be public to the world forever and that the US law will protect you when you make a transaction that is “politically unpopular” by those with power? Or do you trust that US constitutional rights will be strong enough to not send you to prison for concealing where all your UTXOs comes from?

There are no right answers, but if the war on drugs has taught us anything, being on the side that favors a hydra typically wins in the long run. ie. As more privacy tools pop up, with fewer centralized architecture pieces, the harder it is to police whatever the policy might be at the time. Freedom will ultimately win if we have enough people willing to stand up for it.
