Respectfully, I disagree. If you allow someone to stay in the home you live in while you're away, to sleep in your bed, to cook in your kitchen, drink from your cups, and so on, you are most definitely sharing your home. It doesn't matter if you profit or not for that to be true.

I know a lot of Airbnb hosts aren't doing this. They're renting out places they never lived in. There's a big difference.
