If we say "you may collect any data and use it for any purpose" this will not count as consent in the EU since there is not an associated context. Can we craft something that will work for everyone?

I think it means something like "I am aware of DNT but I am choosing not to send you a DNT (DNT:1) request", whereas absence of a DNT header might mean I am unaware of DNT or choose not to send any DNT header at all.
