How can I be a member of such a militia when no such militia exists?
The government is violating the Constitution by failing to have a militia by the way. The first half of the Second Amendment requires the government to keep up a militia to ensure the nation's security.
Your question implies some sort of requirement for me to be a member of the militia in order to have the right to have guns. Note that there is no such requirement. People who are not in the militia still have the right to have guns for private self defense.
Although if the government did have a militia I would certainly consider joining, as militiamen have the right to have grenades, bazookas, and full-auto weapons, as well as the right to keep them at home.
