Bitcoin is a technical solution to what had previously been a political problem. It is not surprising that people in the bitcoin community are more aware than people at large that technical decisions have political ramifications.
Even the normal political problems that governments concern themselves with typically have technical aspects as well as their social values aspects, and while democracy can hopefully allow us to take many different peoples ideas of what constitutes the good life into account, we don't expect them all to have a complete understanding of the technical aspects of each decision.
It's quite possible that random guys might have relevant things to say about the values that inform the block size discussion even if they don't understand the details of the technical discussion.
