People are loosing objectivity in this discussion because they have a relationship/emotional investment in their LGS. That adds value for some people, and those people are clearly willing to pay a premium for it. But from a business standpoint, what MM, CSI, others do to cut costs and provide a better price can hardly be considered parasitic, dirty, whatever negative adjective you want to insert. They have a different business model that they are successfully executing.
Arguing that we must pay more just because we have to support our LGS is the ridiculous argument in this thread. Every LGS can go out of business and I guarantee, FFG will still find a way to get ships to market.
As for saying that the LGS are needed to foster community, I find that specious as well. It is the LGS's responsibility to justify their existence, not the player bases' responsibility to prop them up because a tiny fraction of players like to use the tables there.
Just to add a thought to your point - Hobby Game stores have been around for decades, and yet why has the hobby gaming market exploded only in the last 10-15 years? Because, frankly, online communities/videos/resources are much better at building the market than LGSes have ever been. The effect LGS have on creating market as a whole is a minuscule fraction of what the internet does.
