Guys seriously use your heads.
First of, the reason why Pimax probably can't sell base stations are most likely the same reason why HTC cannot, there just aren't enough of them right now. Neither HTC or Pimax can sell the base stations separately.
When there are enough you'll probably be able to buy them directly from Valve, the base stations are not a Vive product, they are not in competition with each other.
Pimax can not sell you individual base stations no matter how much you complain about it because they don't decide if they can or not. When the base stations actually exist you'll be able to buy them, just not from Pimax or HTC for that matter.
