Health, sure, a TV is easier. But I know a lot of people who say “I would never have a TV in my house” and keep up with the latest shows on their computer. And watch a ton of things. And waste plenty of time.
Its also a lot easier to fall into the trap of watching pornography on the internet rather than a TV. You need to pay specifically for pornographic services on TV, but you can get a multitude of free stuff on the internet.
There are plenty of reasons to keep TV out of your home. I’m not knocking that. But if you have unfiltered internet access, you effectively have a TV in your home, whether you call it that or not.
