The issue with third spaces in the US is making and keeping them fit for purpose. When they tend to be commercialized, squatted on, or otherwise put to exclusive use they are often no longer useful third spaces. What we tend to have is third spaces that are policed in some manner. Often by commerce, as that does a pretty good job of keeping away those considered undesirable without literally calling police. Some call this privatization, which is accurate but overlooks that the money-based gating of access is a key feature.
