I prefer having a third party to ensure quality and have recourse for disputes (it's nice to know that you can sue a company with $1,500,000,000 in venture capital if something goes really awry).

That said, drivers for these services are going to be replaced by self-driving cars.

A robust reputation system using chain of trust scoring to reduce the usefulness of sybil attacks would rapidly result in reliable, friendly, safe drivers building huge amounts of positive feedback, which would then self-reinforce improved customer service efforts to maintain their reputations.

If the online drug markets can use reputation systems to ensure fairplay amongst the vast majority of anonymous blackmarket trades then local taxi networks should be able to manage it too!

If you get ripped off on an online drug market you don't have a recourse (a poor feedback, but hey then you'll get a poor feedback back).

Similarly, I like that I can call my credit card company and dispute a charge. The blockchain style of trust just means you get screwed.

Are online drug markets decentralised?

they increasingly have decentralised aspects (eg. multisig escrow) and the new openbazaar is truly decentralised
