But why follow such an archaic rule in the first place? For all we know, Winter's in the army, and even if she were to purchase shares, the problem is that she doesn't want to be remotely involved inside the business, which is the raison d'etre for her joining the armed forces.

Weiss doesn't want to appear involved either (given from Jacques' perspective, not that he knows that Weiss wants to accept the role and change the company), so why waste time and effort debating and arguing about making her the heir either? Why cause division between the two? For all we know, the chances of Weiss rebelling would be lowered and a source of their mutual antagonism would be eliminated if an emphasis on making her the heiress was removed entirely and that she would be allowed to go to Beacon to the get-go.

And what exactly is the age that the Schnee children are allowed to take the reins? We don't know this for a fact.
