Having flown a properly designed instrument approach, a pilot, at the minima's - and ONLY the pilot - is in the best position to assess the visibility between the aircraft and the touchdown zone and assess whether that visibility is suitable for them to continue the approach. Adding validity to this approach (please excuse the pun) airports across the globe have spent millions of dollars (or whatever the local currency is) to install lights facing up the intended approach path on final. Visibility sensing devices, no matter how highly developed, can never provide better information to a person who is not in the cockpit and, such, we should not prohibit pilots flying an approach to the minima's and making the appropriate decision about continuation of flight.

That’s not what an approach ban is about. Read the first post again! The question is not wether the lights are visible at minima, but wether it is legal to continue the approach in the first place.
