There is a solution which balances site owners' need to track with a respectful consent UX (e.g. no immediate consent prompt): https://transcend.io/blog/defeating-cookie-banners

Many sites prompt right away because they want to begin tracking right away. Transcend Consent transparently converts all unconsented web tracker emissions into local tracking, which can be replayed later with consent.

Instead of prompting for consent on first visit, these prompts could be integrated into the sign up or checkout flow in a website.
