Will we ever run out of Trues

Legit question I thought of. How many Trues (of the good eras that we all know and love) have been produced? Will the supply ever dwindle? How many pairs were manufactured per year, and will there ever be a scenario where these old pairs stop coming out of the woodwork for us to snipe on second-hand clothing sites?

What if all the vamps get bought and none ever get sold again I would be so sad man

Pics is unrelated just me
