According to [1] there are no countries that forbid tx power values lower than 20dBm in the 2.4 GHz band. The lowest value for the 5 GHz band listed is 17 dBm. So why are the Intel cards limited to 15dBm then for both bands? This value absolutely makes no sense in my view.

Are you forgetting to account for the 3 dBi--7 dBi antenna gain?

We are talking about wireless devices that are primarily used in
portable computers. These do not have directional antennas usually. So
there should be almost no antenna gain in most cases.
