Do Not Track is a technical standard that enables users of web browsers to opt out of tracking across websites. Technically it is a very reasonable and simple standard. Unfortunately advertisers ignored the requests not to track, rendering it useless.
A legislated mandate not to track parties that request not to be tracked would not suffer the same problems. In 2019 a bill was introduced into the U.S. Senate mandating Do Not Track.
