You're thinking too small. Targeted advertising deserves to die in a grease fire, but a proper solution is to universally make an individual's personal data their property and require companies to cough up compensation every time it is used in commercial form. Any attempt to sidestep the compensation must account as fraud.
Holding on to user data needs to be a painful liability. The cost of such micro-accounting alone should incentivise companies to keep hold of as little information as possible, so as not to incur excess processing costs. The aggregated cost of payment processing on top of that will provide a secondary cost vector and further discourage using such data. Combine with GDPR and CCPA like power to demand companies to divulge their full accounting details of your data, and all of a sudden the pain becomes real. Not to mention very expensive.
