No, that is not correct.  Being issued resources doesn’t convey any automatic rights with regard to routing:  the network already had the freedom to configure their routers any way they wanted.   RIRs are a source of unique prefixes, and ISPs generally find it easier to announce space they are issued, but what they actually announce and what their peers accept is a business matter.

They may use it entirely internally, and that’s a valid use as well.

ISPs who receive address space already have the freedom to announce any route they want; whether their peers listen depends on each peer.

You want ISPs to commit to not doing something - that is the definition of an obligation.

You have no control over other people’s routers, whether those are in a lab, corporate network, or public Internet.   You never had that authority nor did any RIR simply due to operation of the registry.

We can create an constraint on ISPs with respect to their public Internet routing announcements, but it will require getting ISPs to collectively agree that should be a necessary obligation for participation in the registry.
