I hate ads. I hate them everywhere I see them, but if you want to start a business, and you can’t advertise, how do you possibly stand a chance against entrenched incumbents? Banning advertisements is regulatory capture taken to an extreme.
There can still be product catalogues, people will still shop in person or on online resellers. You can still start off with a limited time discount so people can try your product. None of these need advertisement, they are organic ways of getting the word out there.
