Why? That regulation doesn't apply to non-movement areas.


It applies to runways and taxiways, it says nothing of "non-movement areas".


§ 91.129 Operations in Class D airspace.

(i) Takeoff, landing, taxi clearance. No person may, at any airport with
an operating control tower, operate an aircraft on a runway or taxiway, or
take off or land an aircraft, unless an appropriate clearance is received
from ATC. A clearance to "taxi to" the takeoff runway assigned to the
aircraft is not a clearance to cross that assigned takeoff runway, or to
taxi on that runway at any point, but is a clearance to cross other runways
that intersect the taxi route to that assigned takeoff runway. A clearance
to "taxi to" any point other than an assigned takeoff runway is clearance to
cross all runways that intersect the taxi route to that point.
