alt Hacker NewsThe capitalist economy is based on the explicit idea that everyone will do everything they can to extract value from everyone else, and it'll come to some kind of equilibrium. If you do not do this but you allow everyone else to do this, you receive worse quality products for ridiculous prices and do nothing about it.
In other words, you owe me $1000 as a condition of reading this comment. Your options are to unread the comment, pay me $1000, or pay me nothing to incentivize me to charge a price you'll actually pay (likely $0.00 for comments but not for everything)
Free riders send a market signal of failure or they cause friction. In the former, the service or creator just shuts down and moves on to something else. In the latter the service must make a choice with very little knowledge.. what should they do? Bake ads into the content? Ad block wall? Subscription? Pay per view?
Basically it doesn't make any meaningful progress towards a better outcome. It just temporarily makes the content more enjoyable to you at the expense of the person who created it and maybe to you if you enjoyed it and wanted more.
