DOn't want to get entangled in the political debate, but just a thought:

If you track what MAC addrs use what upstream capacity, you could have data on which to judge who is pushing your usage over any caps you happen to have.

Having some data (not general fears or propaganda generated by those who want to tell you to be very afraid so you buy their gear or their arguments) always helps.

And if you like, you could do something that doesn't involve all the protocol violations that a captive portal usually involves (redirecting DNS, ... and putting MITM attacks on https: connections, ...), e.g. restrict any unknown users to 28 Kb/sec of your upstream, for example, as a way to be non-disruptive.  People won't get netflix or youtube over 28 kb/sec in any useful way.

Security is often just a matter of making it easier to steal from your neighbor, rather than installing an automatic gun to shoot anyone who trespasses.
