What I don't understand is even if there was the most open license
possible, you are requiring to get an authorisation to use the data...So
what's the point of having a legal group or dealing with licensing as if a
restrictive copyrighted dataset that sues anyone who uses the data, if we
have express permission that license doesnt apply to us as we have been
added as an exception to the license.

So if I understand correctly Paul, CC0 or any other license would require
permission as a bypass to the license, even though it would be considered
compatible with ODBL. To me this is why licensing exists, to avoid having
to have to manage each licensing use case and says what you can/can't do
with the data.
