That last sentence was hilarious. Weed seeds are in almost all soil. They arrive there on the wind. What constitutes a "weed" is that it's a plant that's not desired in a specific location. What is, and is not, a weed, is entirely contextual.
The reason for walling a garden is to create a microclimate that protects the garden from the wind. It's like a greenhouse. It's protection for species that would otherwise not survive in the area.
The way to get non-walled technology is government intervention. That's how the internet was invented. Then, as it was deployed and commercialized, it "won out" because it was open, while services like AOL, Delphi, GEnie, Prodigy, Apple's eWorld, CompuServe, and MSN were closed, walled garden online services.
