Yeah, we only have give up any and all privacy. Do you think that drug dealers and gang members will subject themselves to contact tracing? Is contact tracing even legal in the US? Do you really think that US citizens should give up all privacy for covid? That genie would never be put back into a bottle.
Contact Tracing has been done in the U.S. for many decades. Most counties in the U.S. have health departments that perform Contact Tracing for TB and other disease outbreaks. Unfortunately the size and scope of COVID overwhelmed the existing health department efforts and no new funding or staffing was provided to properly scale.
