It was meant more as a joke than criticizing hosting your own services. I personally have a VPN with MFA, and services that I host for my self that are segmented to a paranoid level (home camera system on own vlan, restricted from being able to reach any other vlan or the Internet, etc) with a deny all and explicit allows on per host and traffic type. The amount of work that went into building the network is probably overkill, and it is still susceptible to nation state and supply chain compromise but hopefully whoever gets in will curse me if they try to move around the network.

Realistically, every added service and host is added attack surface and chances for misconfiguration \ supply chain attack, but being alive is a risk too....

I'm guessing system admins and dev op is over represented here so some of our home networks may be targeted as a path into a corporate environment, but I'm guessing the chances are low. Sadly even the most secure networks are not an impossible target. The attackers are well ahead of defenders of networks. Attackers need exceptions, while defenders need everything perfect. Much harder to accomplish.
