Wifi has encryption. Bluetooth means I'm broadcasting my audio stream to anybody who feels like snooping on me.

Not quite.
Bluetooth was originally encrypted, but gained the option of non-encrypted channels with version 1.1.
On top of that Bluetooth use frequency hopping.
Until recently there was no real hardware for scanning/sniffing Bluetooth traffic, at least not anything easily available compared to a wifi card in promiscuous mode.
