The Internet was philosophically designed to move information, and for every effort to prevent that there is a workaround. There will always be a free protocol.

That used to be common in the past, many ISPs ran transparent HTTP proxies to reduce the use of their slow upstream links. The current push to use strong encryption and authentication everywhere (for instance, plain HTTP without TLS has become rare) makes it much harder.
Same as market; anything that does not use it will use less efficient alternatives like politics. Sadly market like tao and politics has no moral either.
