And everyone has money. Their agreement to spend some on your product establishes its value. If it has to be free for them to use it, they are saying your product lacks value.
We can offer what paid services offer, because what they currently offer is not as complicated as they make it look like. Of course we don't have the same infrastructure, fancy offices and 200 employees, but content wise we can produce the same content + add content that isn't our and made available under CC license for example.
Not everyone has money no.

Even if everyone prioritized the service above other things, the things they forego become useless to them – a side effect attributable to charging money.
