What do you even plan on building? Most of the Free Staters probably heard about the project through the Internet. Those people are not going to be interested in dry lectures about Austrian economics, and those that are can just read about it through any number of free sources on the Internet. So much libertarian outreach and community building is done online for good reason.
Do you want to push Austrian economics into academia? Building an economics school with the intent of entering this world won't provide any benefit as the university bubble is on the verge of popping and wouldn't accept upstart Austrians into its brainwash zone anyway. A degree through such a school would be worthless, as it would have no value as a certification since it's not a major school, no value as an academic consensus changer because it's opposed to the mechanisms that enable scholarly rent-seeking, and no value as an education resource because the curriculum can be found online for free.
