It’s meant for you to be completely anonymous. Logging in to stuff would defeat the whole purpose of TOR, as it would associate your activity with the account you logged into. When browsing sites without really needing to interact, it’s good, as the sites cannot track you easily.

There are many use-cases for Tor. One is anonymity. One is to bypass censorship. The most popular website on the darknet is Facebook.
It doesn’t “defeat the purpose” of using Tor in Tibet to access a Facebook page.
