Disagree. Aside from having a storefront or website, anyone could just as easily go to Japan, make relationships with the craftsmen and dealers, return with a couple of Ashis, Katos, Shigs et. al. and sell them for a handsome profit too. In fact, I believe some members here have gone and visited craftsmen like Watanabe, TF, etc... and have come back with nice customs and one-offs that I am sure would sell for a very tidy sum.
Nothing against retailers like Jon or Maxim, I think they've managed to find a way to turn their passion or hobby into a good source of income and we have benefited from their freely shared knowledge and experience. Think those who are butthurt probably did not spend enough time or effort in trying to make some side income from their hobby. Personally, if I could find a way to make some cash or make a living out of my hobby or past time, why not? It brings me joy and brings me cash.
So yes, people like Jon, Maxim, et. al. ARE FLIPPERS, they just do it more professionally.
Also, maybe sarcasm doesn't really translate well over the internet, but my previous post was absolutely meant in jest.
