Clearly, the apartment complex owners could do that if they so choose.  I'm not sure who you suggest should "buy a box from mail boxes etc. yourself and set up mail forwarding each time you set up a new apartment complex" -- the ISP?  How does that help?  This is, as you say, a way to contact the apartment complex owners, right? 

The issues have to do with knowledge and expenditure.  For the most part, consumers and apartment complex owners have no knowledge of IP geolocation or SWIP.  It is consumer privacy at risk here, but consumers have no opportunity to opt out of this scheme even if they knew about it.  "Discuss it with the apartment complex" is generally null advice; apart from the fact that consumers have exactly zero leverage in many markets, the apartment managers (a) don't know about it, either, and (b) can't be bothered to get a PO box and collect the (rare) mail from it.
