Well what? I don't want to be in a club. Why should I?
The simple point being that clubs are organisations and sometimes organisations are very useful at helping to provide structured communication between users and bigger organisations. The velodrome campaign is an example of a time when clubs can be really useful.
In direct answer to your question, of course you can be an individual rider but it is more likely that you will be in a position to give back something to cycling and cycle sport as part of a club.
