The Cabbies may be right. Transport for London, which regulates taxis, has asked the High Court to rule on whether the business model is illegal, a claim which Uber strongly rejects. But if anyone thinks that a court judgement will be the end of it, they are sorely mistaken.
Decay is innate in all things. Entropy is inherent in society in the same way it is found in the natural world.

Equally real civil entropy currently lacks a effective way to manage or even benefit from this organic process.
