I disagree. We only know of the one system which we're in, so maybe it's hard to see something in abstract.
People are good and humane, but also above all are curious and since the beginning of time they are innovating and inventing, with or without patents. No scientist or doctor chooses its field for mone (ok some do). When somebody researches a new drug or a disease he doesn't do it for the money. It's the corporations and other business ventures (whose main goal is to bring profit to its owners and shareholders) that want money so they invest. Which is all legit, I'm all for profit.
Anyway, even now, as is, there are numerous for profit/non-profit organizations and foundations that invest into drug research, finding the cure for diseases and so on. I think Mark Zuckerberg is investing in free internet in poor countries knowingly they won't have the monopoly from it.
Imagine how it would be there were no monopolies & patents for it (or not in the degree we have atm) - would those who give money to the above cause stop or flourish? If there was no other way of innovating but investing, wouldn't we invest in those branches even more? Monopolies demotivate that. Why would i.e. Bill Gates give a billion dollars for studying breast cancer when he knows Pfizer will do it for him? In the current state of things, it's logical people won't spend money on something when they know somebody else will (driven by profit) and of course, innovation will happen only where patents are possible. Since the Pharma is the major player in drug innovation, and they are protected by regulation, we have no other choice except them. There is also an option (if there were no state enabled monopolies) of public funding or subsidizing innovation. Why the hell not? Maybe the government would have spent less money on subsidizing inventing cure than paying health insurance for costly drugs. Crowdfunding is a way as well.
All of this is not visible and therefore people don't see it, but there are ways and options.
Luckily for us, the wetshaving market is not regulated like that. Imagine there was only one company making DEs. Nobody else has the right to make it. they patented gazillion designs. What then? If there are alternatives (straight razor, cart) great, we can switch, but if there are no alternatives - the producer could charge a simple plastic DE 100$. And you have to buy it, you have to shave.....
Also, what I said earlier - patent in the current system do spring innovation, up to a point but monopolies can actually hurt innovation or slow it down (Tabbarock Curve:
http://www.rationaloptimist.com/blog/the...rok-curve/ ). If there are limited players on the supply side they control everything, what to produce, at what price to sell it and so on. It's not in their interest to invent cures for everything at once, but if there are barriers to enter that market nobody else can come in and they can do whatever they want. Not only that, but the consumer/insurance is paying the drugs maybe far more than he should and all that money could have been invested in R&D. Patents cost, probably a lot. All that has an effect on the final price of the good and the money spent for it could have been spent in innovation. Same can be said for a DE razor.
Actually, it's rather simple: The best evidence there is innovation even without patents is just in front of us.
New DEs are being invented all the time. DE, SE, injector, GEM, new synthetics brushes, knots, handles, soaps, whatever - can someone deny that?
If none of this makes any sense, then by all means: If you want to create a DE nobody can copy - apply for a patent. It'll cost you money, so charge the razor higher and hope nobody else will invent something similar. Probably not gonna happen. Thank god for us.
If it's something that took a lot of time and effort probably it won't be easy to copy it, especially with a patent. If a DE is rather simple to copy, probably your alleged cost and effort of R&D isn't so great in the first place. If it's a fine tunned adjustability mechanism in question or a special kind of donkey milk taken from a special sort of special donkey who eats special food probably you won't get copied too easily, cause it takes time and money do copy such a thing.
So maybe don't make razors. Do something else. Or don't give the production to the Chinese in order to minimize the cost and then cry to me that they took your unprotected design. Find the best business model you can, try doing a Kickstarter and offset your R&D cost (Rockwell, Model T) change it, adapt it. Noone can guarantee you anything. It's the way the world works. It's a suppliers problem, not the consumers, why should we deal with it?
