It isn't usually a question of efficiency, it is a question of damage. Technically there is an argument that something like the holocaust was inefficiently executed, but still a good reason to actively prevent governments having ready-to-use data on hand about people's ethnic origin.

A lot of the same observations probably apply to the ICE situation too. One of the big problems with the mass-migration programs has always been that there is no reasonable way to undo that sort of thing because it is far too risky for the government to be primed to identify and deport large groups of people. For all the fire and thunder the Trump administration probably isn't going to accomplish very much, but at great cost.
