To live peacefully in a society you have to compromise and you can’t just do as you please. Communities have certain standards and by-laws that should be respected. If you’re compelled then bring it up at the next town meeting and rally support for your cause.
What if someone decides they should park their car on the front lawn since the boat and camper take up the driveway? Or just set a couch up on the front lawn because I like to have a nap there?
Can your neighbors also prevent you from putting your children sculpture or garden gnome in your garden because it's not up to their grand standards?
Putting indoor furniture outdoors is inappropriate as it isn't made for outdoor use. It will grow mold and rot and fall apart and it will become a nest for rodents and attract insect colonies that can spread everywhere. It will smell bad and reflects poorly on those that live nearby. I wouldn't buy a home in an area where I saw something like that. If you were to poll my neighborhood (granted the average home is over $1,000,000) I guarantee everyone would agree. Even where I grew up which was very blue color, you wouldn't see anything like this and you could be certain a neighbor would have a talk with you if you tried.
We don't live like that.
