I don't agree that regulated markets aren't sufficiently adaptive to social change. Silk Road was also a regulated market, just one that dealt in mostly illegal narcotics - so this clearly was adapting to the liberalisation of drug laws that is desired by so many.

But if Silk Road had also dealt in child pornography, for example, we can be pretty sure that most people would know about it as a haven for paedophiles, rather than an online drugs den.

My point is that purportedly neutral technologies become best known for their predominant use case. The Internet is mostly synonymous the web and email, as these were its first killer applications. Bittorrent is notorious for copyright infringement, as that is what it is overwhelmingly used for. Bitcoin has connotations of being a get rich quick scheme crossed with illegal drugs currency. And so on.

Despite its intentions of neutrality, as an anonymised, unregulated, decentralised market, OpenBazaar will most probably become known for facilitating illegal trades - of all types.
