As someone else said, for WPA, you can't simply spoof the home base. You have to know whatever password the device is configured for. And even if you did know that, you'd have to spoof the same MAC address for most computers to communicate with the device, which is more likely to just break everyone's internet connection, since the whole communication protocol relies on MAC addresses being unique.

Once again, the only way they're going to auto-connect to your network is if you have the same MAC address and password, and the interference would kill you. You're more likely to get fish on the hook if you make an AP with the same name and hope you trick some people who are frustrated with you shutting down the other network into trying it.

Not if you actually use WPA2, pick a good password, and make sure your users aren't connecting to random unsecured networks with the same name.
