Lets run the clock forward a few years ... Plugins like Metamask are common place and Smart Contracts can be accessed in a URL type format, posted as a HTTP links etc.

All the technical barriers are removed and even unskilled users can post images & PDF's etc into the public blockchain for anyone to download.

What happens when the general public starts adding real nasty stuff to the blockchain? Kiddie or terror stuff etc.

Can a vote be taken to remove a smart contract? What happens if large nodes start saying I don't want to store this data on my servers? What happens if Law enforcement starts saying remove this content or we'll just go after the whole blockchain etc.

Legitimate question.
