I don’t think this is the right analogue. Having someone come to your door breaking things would take much larger effort, and easy to be caught. But DDoS or attack your service has minimal cost.
Visiting sites and sending the IP address is not the problem, the router has firewall and basically blocking unwanted attention. But when you expose something without protection and allow someone to burn your CPU, or, in a worse case, figure out your password for a not properly secured service, is a totally another issue.
I saw people setting up honey pot SSH and there are so many unauthorized access and I got scared. I think exposing entire machine to network is like you drive car without insurance. Sure you might be OK, but when trouble comes, it will be a lot of trouble.
