That title is a dirty great lie. This page doesn't describe a perfect world and never will. It's just some ideas as to how it could be better.

Money and economics

Some practices which are currently legal, such as short selling, would be criminalised. See how to make money.

Other practices which clearly advantage the rich over the poor, notably inflation and complex tax systems, would be seen as the evils they are. Fair ways of making money would be encouraged, including investment, sound management, self-improvement and plain hard work.

Taxes that discourage division of labour would be abolished, so that the community and the individual both received maximum benefits from their skills, training, tools and so on.

Wealth and the use of it to create more wealth would both be seen as good things, to be encouraged. But abuse of wealth would be seen as evil. 

This is the very opposite of Marxism. Marx correctly identified the abuse of wealth as a problem. But his solution, to abolish wealth, is arguably worse than the disease. For one thing, as The Who said (paraphrasing George Orwell), Meet the new boss, same as the old boss... it has proven impossible to actually do it, a new aristocracy just reappeared, with their name changed but not their abuses or even their tactics. In glorious hindsight that's not surprising. And just as important, it makes it appear that the problem has been solved, when in fact it hasn't been even partly addressed. The new problems it introduces include all the old problems, just by new names. 

Intellectual property

Patent law

Patent law would be enforced. For example, pharmaceutical companies that refuse to license drugs at an affordable price would find these patents declared void in the affected regions.

Some executives would be warned that any further deaths attributable to their failure to license on reasonable terms would be prosecutable as murder. 

There is some evidence recently that pharmaceutical and other medical technology companies recognise that failure to provide reasonable access is indefensible both politically and legally. That is progress. History will judge why it has taken so long.  

Copyright

Copyright law would be enforced. Publishing companies that issue fraudulent invoices or post fraudulent copyright notices on their publications would find their copyrights voided by these actions.

An international repository of copyrighted material (of all forms and in many digitised formats) would be established and available on the World Wide Web, and therefore searchable. Adding material would be free of charge except that anyone lodging derivative works of material already in the repository would be required to declare this connection, and pay a reasonable royalty to the owners of the copyright on the works used. These fees would cascade... When a derivative work was itself used and royalties paid, 50% of these royalties would be paid to the owners of the works used in the derivative work, and so on down the line.

Fraudulent claims of derivative connections (you cite your friend who cites you etc down the line, or make trivial changes to a work and claim it's derivative) would simply result in the forfeiting of the royalties (which would help pay for the investigations) and removal of the material. Failure to declare derivative connections would be similarly (but fairly) dealt with... Sometimes, you really don't know where that tune in your head came from!

And there would be a system for deciding that a work is truly derivative, not just a trivial modification. People lodging borderline cases could apply to have a smaller than 50% share of the royalties, and would be encouraged to do so. People making a minor use of other works could similarly apply to have a greater than 50% share (they will need no encouragement). And there are more complex combinations of these possibilities. Yes, there's a lot of administration required!  

But the goal of it all is not to punish wrongdoers. The goal is to make it unattractive to do wrong in the first place!

It's not perfect, just a lot better than the current system.

And a byproduct would be to spur (and I suggest even sponsor) research into new search tools. Text searches work well. Image searches are beginning to work well. Music searches are still in their infancy, and many other information formats not even that.   

Substance abuse

Adults would be given the right to use recreational drugs if they wish, but children would be ruthlessly protected. Is this really possible? Only by implementing both of those proposals, to put the drug barons out of business. See a dream about drugs.
