The web is a public space - it's not your property or your front yard.

You're wrong here. Just because it's a public space does not mean nobody owns the property. As a simple example, a shopping street is usually a public place. That does not mean that all window displays, doorways and adjacent buildings are automatically a free-for-all.

In fact, only "the tubes" of the web are a public space. The rest is owned property, even if there are no visible fences.
