Are you arguing that any service offered over the internet is tacit approval for *everyone* to use that service?
Yes. Although I would substitute 'attempt to use'. Any program listening for traffic on a public ip address should expect contact from any other public ip address. It's not controllable from the listening end. Access control is the responsibility of the service provider. Connections can be restricted based on many criteria (IP, password, token, certificate, etc) if desired.
Assuming that my interpretation of your writing is correct, you would support unsolicited bulk email. After all, you have an email address and your mail server (or the firewall through which it passes) has a public IP address, right? After all, I got your email and I'm not on your private netweork.
Oh, sure, make me support the spammers. ;) A spammer has just as much right to send a syn packet to my port 25 as anyone else. I don't need to accept the connection or the message. I can set up a mail server that will only accept messages from a special 'white list' of senders. Or one that requires SSL with client authentication. I can still complain about most unsolicited commercial email. It is usually a violation of their TOS.
