No more so than License Plate Numbers are purchased/rented/etc. from
the DMV* (or whatever your government structural equivalent).

ARIN provides number resources which are known to be globally unique
among the cooperating entities collectively known as the RIR system  
includes IANA, 5 RIRs, and a significant portion of the ISPs and end  
who subscribe to services from the RIRs and choose not to attempt to use
addresses on the global internet which were not assigned to them by an

system and route accordingly certainly makes the internet function

has any way to prevent them from doing something else.
