For me, if I can't get 2k per week out of this guild, then go ahead and kick me because it's not working out for me either. For guilds that require 20k in sales or something like that, then steer clear if it's not your thing, but it would be a big mistake to pass on a guild with a better trader because of a 2k min. 2k just means you have to list something, it's not really much of a requirement.
One example: list ANY gear with a trait (level 1 is fine) for 100g. People will grab it quickly at that price for crafting research. 20 of those and you're done. It's impossible to play and not get that. You just have to list them, which is what you want anyway.
