So the real difference is between collecting preorders for something you MAY be able to fulfill in the near term vs something that you may be blocked from selling for an indeterminate amount of time.

Starlink will eventually be legal in India, but it could take decades. In this sense, there's no real difference between "avoid selling things until you can provide those things" and "avoid selling things until you are allowed to sell things". It's just that a normal person has a cutoff point where it becomes an unreasonable wait.
