"The additional cost to mine the asteroid and return the ores to Earth would make profit unlikely even if the asteriod was 20% gold."
They could simply leave the gold on the moon (makes stealing it a big expense), prove that it exists, and sell it to central banks here on earth; AFAIK central banks have a lot of gold in storage. Then these no longer needed reserves could be put on the market, but an additional 100 tons of gold will make the price go down, making it even more unprofitable. Whatever their decision, price will go down.

To make it clear, this is a tax on the *private copying* of the copyrighted works purchased.

"PROJECTO DE LEI N.o 118/XII
“Aprova o regime jurídico da Cópia Privada e altera o artigo 47.o do Código do
Direito de Autor e dos Direitos Conexos – Sétima alteração ao Decreto-Lei n.o
63/85, de 14 de Março"

This proposal is to update the current legislation in place on copyright. It's an attempt to reinforce it to compensate authors for the legal private copying that occurs of purchased copyrighted works. It has nothing to do with piracy!

IMO the spirit of this this it to put piracy and private copy at the same level; after all the copyright holders are not compensated for these copies, be they private/legal or illegal!

It is appalling that our legislators (I'm Portuguese) can come up with this sort of proposals - as if an 1 TB drive will always hold 1 TB of copied copyrighted works; as if I should keep paying for works I purchased and/or others purchased!

Also, IIRC, the money collected by this tax is to be managed by an external entity, not the government, and distributed to authors - I have yet to see how this has been done in the past and where the money has landed.

If you want to know more, and are able to understand Portuguese, search "118/XII".

Not a book, but a must read for anyone working with computers.

If the purpose is to avoid roadside bombs, why not develop an UAV dedicated to that purpose?
It would also help with the clearing of minefields.
