It makes me consider who is really making decisions & who is giving permission. In the USA scenario ATC gives permission to land IF the captain considers it safe to do so. The decision is the pilots'. The same should be true of GA's.
This concept is reinforced by this type of scenario: Heavy takes off. B737 is given line up & takeoff clearance. Captain of B737 rebukes ATC for not knowing they need 2 mins separation. ATC replies, correctly IMHO, "I didn't tell you to takeoff I cleared you to take off. It's your decision." I've heard this at UK airports.
