Perks of a privacy law with some standard of data minimization:

1) It doesn't violate the U.S. Constitution ✅

2) It helps avoid embarrassing security breaches, or if there is one, less information will be revealed ✅

3) The data can't be used by some wacko state to enforce an unjust law, or other form of persecution ✅

4) Less data to be used for marketing purposes ✅

5) It helps protect someone's privacy more generally ✅
