The problem with taking away starting gold is that you probably take away an equipment list as well, or at the least, the ability to browse it.
And that indicates that the designer has no clue regarding why a game has an equipment list.
The primary reason I see for having starting gold is to prompt the player's into different directions regarding the ways problems might be approached or solved. So for example, my equipment list not only has a lot of different sorts of equipment for solving mundane problems, but explains their use such as, "Virtually all sentient species enjoy wine, and offering to share wine is a commonly recognized gesture of good will which may result in a more favorable reaction." If your equipment list doesn't have ideas on it like chalk, crowbar, dice and cup, limewood strip, magnifying glass, listening cone, grappling hook, wool blanket, soap, whiskey, salt, aniseed, iron spikes, 10' pole, and so on and so forth, you are really not IMO pushing the game in a very creative direction at least with regard to a player's approach to solving problems. You are also probably not signaling to the GM or the players that creative solutions will or should be rewarded, and instead that the game is about killing things and taking their stuff and even kicking down doors isn't part of the process.
