I think you've got it right, for the most part. People are going to be afraid of someone they don't know, even if they are a part of their village, having so much power. But not if their Kage throws a beast inside of them! Because, well, the Kage is loved by all o.o Or, should be.
See, for me, and even for Riku, I know the beasts are more than just trophies. IC, Athos and Saiken are best friends. Saiken cares about Athos' well being, talks to him, tries to get him to stop being so quick to action. To me, Saiken is more than just a trophy. He IS a plot device for me.
I can't vouch for others and their beast, but me and the Six Tails are different. More than just trophies, or power sources. Hell, let's say the Six Tails didn't actually give me it's chakra or Bijuu chakra couldn't be called upon, right?
I'd still keep the Six Tails because of it's relationship and plot device. Hell, that's why I got the Six Tails back. The five just wasn't me and felt only like a trophy, I couldn't work him into my RP no matter how hard I tried x.x

Boooo xD haven't you read the newest copy of the Ninja Handbook? Being a Ninja is being loud, proud, and screaming that you're here when you are there xD
