From the time-of-day you have replied, I have to assume you are in Europe or the UK, whereas this discussion is about the US (if you are in the US, I would have to assume you were misinformed or trolling), so ...
1) Monopolies can pass costs only as so far as they have become essential monopolies - like the power company, Microsoft, US health care or phone companies. But 99.9999% of patents are monopolies on _inessential_ things, which the customer can just avoid if not competitively priced, so they CANNOT pass it on. New cheese making patent may give monopoly on a new cheese kind, but if not competitively priced would keep customers with their old Camembert.
2) that has already happened, that's why in the US, the patent office is already a rubber-stamp, patent examiners have 8 hours to review a patent, and are encouraged to accept the patent rather than reject it.
3) Patents are at the top of the legitimacy scale already in the US. Unfortunately. Which is what Cuban (the original article) is talking about.
4) Well, patents don't do that any differently than anything else. A company could just as well buy a house for $100K, claim it is worth $100M, pay property taxes to the local council, and claim "huge value". If someone is going to be this fraudulent, it doesn't matter if they do it with "house", "patent", "copyright", "trade secret", or any other "property".
You could probably go on, but nothing you mentioned is relevant to the discussion of patents in the US (which is what the original article and my proposal is about), and very little (3, maybe) has any bearing on that discussion in Europe.
