You're not obliged to make a topic, OP. In fact you might even spend years/decades just reading around here and/or replying to some threads rather than being able to create topics. Last topic I created was like 3 years ago about the incident in my account and that was it.

I do not have that much time to maintain and keep up with the discussion/s so I just refuse to create one and that's totally fine. Similar to my experience in Reddit where I almost never create topic, just reading around subs.
