You and Paul are both claiming it's extremely hard.
A restaurant won't scale - most ideas won't scale - because they're not useful enough.
These companies are not criminal enterprise and they don't steal money or threaten them with violence: they just offer them products and ecosystem and most people are dumb enough to ruin their life with it. Don't get me wrong: I hate them and I ban social media for my kids, but it doesn't make them evil.
The bad actors are thugs with guns stealing your purse and the government stealing your tax money or threatening you with jail.
To give another, less controversial example, I don't think companies selling products with sugar and seed oils are bad, even though they likely have the highest combined reduction of life expectancy across all people - but I hate them too.
