weird metaphor, if it was actually shoes then the left shoe owners could be expected to make a right shoe next (if they need a pair of shoes and not urgently). It also seems like the pair of shoes just wouldn't be sold (market failure) if the right shoe owner demanded $99 and if all of the left shoe owners are actually trying to run a business. Maybe one is doing it as a hobby and giving up their shoe for free so the profit-seeking right shoe owner gets to keep all $100 (that's a metaphor for open-source software) but I think in reality all the left shoe owners would hold out until they've made matching right shoes.
