To be blunt, because it sounds insane and simultaneously solving the problem at the wrong abstraction level, and based on criteria that have nothing to do with age. Age-based IP ranges? This sounds like a recipe for reinventing the entire internet in a non-backwards-compatible way. Networks are not people. Why would we treat the network as your identity?
What strikes you as unreasonable?
What I'm suggesting for different service levels is simply to map a specified access / age-verification level to a specific network access point. This is better suited to IPv6 which has a much larger address space than IPv4, and often allocates a range of addresses rather than a single IP, though NAT or IP shenanigans might be possible for the latter as well.
The point is to put the heavy lifting of age validation at a level at which who is getting the service has already been vouched through service account provisioning.
