Tell me, when have Harriers operating from land bases used VL? Since when has it been necessary to use VL for operating from austere bases? You strongly implied that it was not possible for F-35B to operate from austere land bases because it couldn't land vertically at them. Now you're using different arguments, none of which disqualify F-35B from austere land basing.
Note that other fast jets, which have no possibility of performing a vertical landing, routinely operate from single runway bases.
