I do understand the point, but other then allowing a process of auditing to allow a middle ground of consent implied for first-party use only and within some strictly defined boundaries, what else can you do? It's a market for lemons in terms of trustworthy data processors. 90% (bum-pull figures, but lines up with the number of websites that play silly buggers with hiding the no-consent button) of all people who want to use data will be up to no good and immediately try to bend and break every rule.

I would also be in favour of companies having to report all their negative data protection judgements against them and everyone they will share your data with in their cookie banner before giving you the choice as to whether you trust them.
