I don’t see how you can prevent others from collecting your data without laws and enforcement, which seem to be hard to pass and maintain (see: GDPR and right to be forgotten. Sometimes they work, but sometimes they don’t, and they have their own issues).

The technology is already here for people to collect and publish their own data. Most people in the US can purchase their own VPS, host their own website, use federated media and self-hosted services. Lots of sites and institutions let you request your data, though sometimes the process is obscure, and you can scrape any data about you that is visible to you. The main obstacle here is that it seems the vast majority of people aren’t interested, I wouldn’t expect a layman to even know what “self-hosted” means.
