Like a sibling said, you misunderstand these laws (there have been more than one, but the main one now is GDPR). I never heard of a law where you needed a privacy wall to inform people about some technical features of how the website works. It's only when you store tracking tokens in the cookie jar, localStorage, etags, etc., that you need to tell them what data you are collecting.
If you do not need opt-in consent just to view the page, then no coercive wall is ever required.
Literally every single one of the sites with so-called cookie walls can be divided into two categories: site owners that have no idea what the law actually says but they think it's trendy or something, and sites that have no legitimate interest or other legal reason for processing some data and therefore need to seek your "freely given" opt-in consent. If they already had a legal grounds, they wouldn't need to ask for it.
