[MCU] How does the economy of Wakanda work?

In *Black Panther*, Wakanda is demonstrated to have a thriving post-industrial economy, with bustling streets filled with vendors and market stalls. 

What do Wakandans use for currency? Vibranium is the most obvious candidate but how do they determine value and and ownership? According to Klaue, there is no scarcity of vibranium in the Great Mound below ('they've been mining it for thousands of years and haven't even scratched the surface'), so the only limit on the availability of vibranium is the rate of extraction, which has only increased, especially after Shuri's advances in technology such as sonic nullifiers and automated maglev trains.

Who owns the Great Mound? Is it the personal property of the Royal Family, or is there collective ownership amongst the four participating tribes? What system governs the distribution of vibranium? 

Presumably, labor could be exchanged for value-added vibranium-based products (technology, clothes, etc), which not every Wakandan is capable of creating.  But as demonstrated, Wakanda is basically a functional post-scarcity economy. Why are there people down in the streets in the hot sun hawking snacks and textiles if they could all be philosophers or artists instead?

Because some of those street hawkers ARE artists. Textiles are art. Cooking is an art. In terms of tech, medicine, etc., Wakanda may be closer to post scarcity, but They're not there yet. Even in utopia, you still have to eat. Food has to grow. Someone needs to cook that food. Someone needs to sell the clothes you make as an artist, and maybe they only work that stall part time, or maybe they only do it to see people, to be part of the community. Wakanda works, and wakandans work, because doing so improves the lives of everyone around them. 

Vibranium isn't rare in wakanda, but it isn't toilet paper either. Think of Vibranium as the rare earth metals in your phone - expensive, used in small quantities, and not wasted on something as simple as coinage. vibranium is also controlled. They try hard not to let any of it escape Wakanda. Why would they use it for something as disposable as currency?
