The lab became a value-added partner in the market's supply chain

A commenter named disglem said this in PowerLine about the connection between the biolab and the wet market in Wujan.

I think the jump to humans was designed-in. It's a feature, not a bug.

The mass exposure at, and transmission through, the Wuhan wet market happened because that market is the primary client for the hundreds of pounds of exotic delicacies (deceased lab animal meat) that the lab has on hand every week.

Tons of valuable product, tens of thousands of dollars worth. Every week. Do you believe it would be thrown away? I don't. Wuhan is an enormous city of 11 million people. That's FOUR TIMES the size of Chicago! The very-rich are always eager to serve something "different" to their party guests. Caterers and high-end restaurants compete to meet that demand. The wet market serves the food preparers.

From shortly after the lab was opened, and became a value-added partner in the market's supply chain, everyone connect to it would have to have known this was happening.

Suppliers in the countryside, who probably previously sold the exotic species directly to the market's buyers, now had a client (the government lab) who paid better.

On the one hand, the lab had a ready-made supply of unusual species, and on the other, a means of repurposing its waste products that would produce a steady supplemental income to share among those lucky staff, researchers, administrators, and security personnel who found a way to take a slice of the pie.

We'll never know for sure, of course. This is just my guess as to what went on.
