That would've been more true 10 years ago. Now, the overwhelming majority of HN users make their living in yet another business model that exists increasingly because of the relative obsolescence of the previous business model - namely, by shifting into the $foo-as-a-service realm.

The wages of all those people wiring up form fields to databases for cat sharing companies are propped up --- drastically propped up --- by scarcities engineered into the economy by copyright.

How do you figure? Nowadays, a very large majority of web devleopment primarily consists of taking some collection of open-source tools and other services in order to create a service. The entire justification for the existence of such a service is the idea that most people aren't inclined to do all this themselves.

This isn't a matter of scarcities at all (other than the time of the end user), let alone engineered/artificial ones. It's a matter of "I'm too lazy to setup my own web server to share my cat GIFs, so I'm gonna just use Imgur instead, since they've already done the hard part".

I agree. "It is difficult to get a man to understand something, when his salary depends on his not understanding it."

Not really. You can't copy SAAS (assuming we disallow e.g hacking into servers, which seems fair in so far as you also can't read my diary, since it exist exclusively in my house). You can't copy a cloud system and you cannot meaningfully copy hardware.
