You can actually. Right now, you can still delete if you post has no comments or votes. They only remove the ability after it has gotten attention...

Good to see people talking about this, it is trivial to change back.

It's ok about not deleting your post, because it's in the blockchain and must be visible as a proof of stake. But as long as there are eyeballs, there should be payment.

Satisfaction that comes from consuming the content is the payment that it gives to the consumer. It doesn't always have to be a monetary payment.

Of course. Monetary payment comes only if the reader is voluntarily engaging in it, by commenting or upvoting. But right now if the reader wants to engage in something like that, the author doesn't get anything. And that lowers the value of the network, in total.
