True, it's probably overkill. But even if you don't log, they could theoretically start live monitoring the VPN with a court order... With a setup like this, there's no front door or backdoor, just an ephemeral image you have to restart to modify. You'd have to write in access methods and rebuild to get in... The government can't just walk in and demand you stop what you're doing and build something for them
It does add security, even if you might not need that level of security
