In my ideal anarchistic society it is fine to do that. After all, it would be unjust to force you either way to do a particular thing with your product (labour time). But nobody would choose to do that, as they would know that their labour is being exploited. All wage labour is like this, provided that you are selling it to someone with the express intent for profit. In a society that has prisons and punishment, though, those who exploit labour would be treated the same as those who steal or force people into unconscionable contracts. The profit motive as shown through history has almost always caused massive environmental damage. Labour standards merely give the illusion of a world without exploitation. In reality your prpgrammer in SV is exploited the same way, but to a lesser degree, than the sweatshoo workers.
