However that is assuming any one looking to counterfeit a product would have the ability to open a factory, manufacture
Thinking that this is hard to do once again points to an outdated thinking style. It's really easy to make incredibly cheap knockoffs, and there's already a very lucritive business doing it. The only thing keeping it at bay is trademarks, copyrights, and patents. If you go to a country without as strict a policy on those things and you'll find the items everywhere.
then reach out to major retailers nationally/internationally. It also assumes that retailers would be willing and knowingly pit low quality products against products that they know is a quality product.
sure, some retailers would be willing to knowingly sell counterfeit products at a quality level price in order to expand their profit margin. however these same sort of retailers business models frequently involve employing poor customer service and bad PR. They are out there, and im sure we could name several. However the reason why their able to stay ahead in the retail economy is another unbalance in economic regulation.
Once again, you're thinking in terms of the reality as it is now. That reality comes crashing down once you get rid of the only protections in place... http://www.bbc.co.uk/news/technology-14503724
BTW: a good amount of the modern technology and medication we enjoy in our society would never have come about without patents. There are those that abuse it, yes, but there is a lot of capital-intensive R&D done because companies know they have 14-28 years to recuperate their losses on a new product. We've benefited from this greatly.
How on earth did it end up the case that I'm the one defending patents in this thread?
I have a, possibly peculiar, perspective on Intellectual Property: I think it's a lie. My own belief is more in line with Newton's sentiment when he stated that: "If I have seen further it is by standing on the shoulders of giants.". I see knowledge as an organic living thing that stretches way back into the past and hopefully way off into the future. The notion that someone can claim right over one momentary part of knowledge doesn't sit well with me. Obviously a business needs to recover any capital investment and generate profit to innovate. But to extend protection of, what are purely business needs, to the realm of human knowledge in any way that acts as a barrier to curiosity or intellectual endeavour seems counter-productive in the long run.
Trademarks and copyright don't have any negative impact on human knowledge.
In order to apply for a patent, you must disclose your knowledge in a written form that anyone can read. A proper patent system would only boost human knowledge. The only problem is that the current patent system is broken.
