Don't blame the legislators for malicious compliance. Don't set cookies (which is the perfectly reasonable thing to do for read-only visitors of many sites) and no consent is required.

You can set cookies. You can store data that's required for your site to function. You are not required to ask anything when doing that.

For storing more than that and especially for handing user data off to greedy advertisement leeches you must ask for user consent.

When asking user for consent, opting out must be as easy as opting in. If the user opted out, the site must continue to provide functionality.
