Most of anthropic's money comes from enterprises that may want to enforce something like this at an org level.

As I pointed out above, Anthropic places a lot of requirements on its users already, but if Claude Code TIP were optional, presumably, savvy users would turn it on voluntarily, unless they wanted to use Auto Mode. As Anthropic's study clearly documents, the current manual approval workflow basically doesn't work at all, because the users just approve 87% of dangerous actions. So there's no reason to use it, except maybe very rarely.
