This reminds me of Gillette or Keurig. Make a common product or need disposable. Why? Not to fill a need or create a new service/method for doing something. Just, because, that's why. Nickle and dime the consumer by preying on their laziness and putting a shiny package or vibrating handle on it...
That specific market story is even worse since cartridge razors and canned shaving creams or gels generally provide an inferior shave for the majority of men. The only major benefit is that they can be used without any skill or practice whatsoever and the modern version may shave a couple minutes off your morning shave.
On the other hand, a safety razor will last you a lifetime, replacement blades have been standardized for close to a century and even the "premium" brands cost less than $0.15/blade. A nice quality safety razor and wetshaving set can be had for about the price of 6 months of cartridge razor replacement blades, and beyond that, you can probably buy a lifetime supply of safety razor blades for around $200. Shaving cream will cost you about the same either way, so it's not a factor.
I happily use a safety razor, but I won't pretend that it's any more convenient or necessarily gives a better shave. I always found that my disposable or cartridge razors worked quite well, and shaving cream is of course a hell of a lot easier than whipping up the soap.
The convenience of a modern razor, including the fact that it's much easier to learn, makes it worthwhile. Everybody on HN is always talking about how they simplify their lives by throwing away everything except their macbook and a few day's worth of clothes or whatever; I think for most people the simplicity and ease of a disposable razor and a can of shaving cream beats saving a few bucks a year.
