Exploring the Package Contents

As you Mac users / app hackers may know, you can view the contents of a package (application). In Second Life:Contents:Resources:trial, I found a bunch of web page files with intersting contents. Here is the contents of purchase.htm:

"With a paid membership you can buy, sell or trade land and objects. Whether you want to become the wealthiest purveyor of highspeed jetpacks or are looking to buy the perfect custom tattoo for your avatar, the Second Life economy is booming. But you've got to be a resident to start building your fortune. Upgrade to a Second Life membership now and go shopping or put some wares out for sale."

Are you not allowed to buy, sell, rate, own land, teleport, script, and all of those other things in the trial?
