The rest of the world isn't like your little isolated Brazilian tribe where women are topless. Most of humanity's cultures have women cover up their breasts in public.

You would be flushing your respectability down the toilet, and every time you leave your house there's a considerable risk of random guys walking up to you unprovoked and saying things like "hey you're Twitch booby-streamer no. 10455, i really liked it when you grinded on that teddy bear when fortnitehackrfan666 donated $30 USD in your stream!"
