Your lawnmower (your website) is in your backyard (your servers). If I go to your backyard (your servers) and I get/use your lawnmower (your website), I'm 1) trespassing privet property (the paywall) and 2) using something that I'm not allowed to use (your lawnmower, your website that requires me to pay for the content).

No matter how easy is it for me to go into your backyard (bypass your paywall), it's still an offense.

If I can download your content by simply changing my user-agent identifier you don't have any security. In this context the backyard is the local computer and web browser. The lawnmower is the content in question. It is deposited and there. If you don't want the user to access your content then don't drop it into their backyard. The user isn't trespassing by accessing content left in their property.

More simple, if you don't want the user to have it then don't give it to them.
