Yes, but I'd ideally go to a licensed, brick-and-mortar store for the reputation and reliability over either eBay or Craigslist, if it weren't for the prices and availability of items. My point is that the benefits of centralized, non-blockchain solutions can outweigh what you lose when you go decentralized, and that's something that should be questioned of every new blockchain application.

Yes. Good point. It's an interesting thought experiment.

What if the broad spectrum of Craigslist service providers included car drivers who could (somehow - hand wave) offer rides on Craigslist?

How much confidence would you have in them?

What condition would you expect their cars to be in?

What kind of driving record could be expected from the drivers?

How would you choose a driver from that spectrum?

Would you expect to pay less or the same as for an Uber ride?

Under what circumstances would you just avoid using a Craigslist driver altogether?
