Re: Not silly at all
I think in the case of copyright material, production and distribution of digital media online can be done with relatively inexpensive equipment, compared to the physical offline copies which require expensive reproduction materials, storage and distribution costs.
In other words, it's comparatively easy to set up as an online pirate, and more difficult to detect and stop. It would seem that threat of penalties is the only weapon that the lawmakers can come up with to deter it.
I'm not justifying the whole thing, just recognising that digital and physical are different.
Of course, with digital a pirate could set the whole thing up off-shore in a pirate-friendly territory and carry on business as usual without breaking any UK laws.
