Sure you can. You can pass laws that require companies respect a 'do not track' setting in browsers and don't collect data or make you jump through 'accept cookies' hoops. You can make right to repair laws. You can pass laws that require interoperability like making phones use a standard cable (they did this and I think its great). You can pass laws making companies like MS at least make available a no-tracking, no subscription, no ads, no telemetry, no bloatware, no AI, no bullshit version of windows OS for regular individuals at reasonable cost. They can do stuff that like that.
