I agree mostly, but then NO locked or self-moderated threads should be allowed in Digital or only HERO or above should be permitted. Sure, people should be smart enough but why give a scammer such an easy place to setup a scam?
Locked and self-moderated threads can help clear spam and are clear indicators of potential scams. If you see the warning - where your posts may be deleted - you should peruse the forum for the trustworthiness of the individual, either by asking in the thread or by checking the Scam Accusations section.
I have no problem with people learning their lessons the hard way or the easy way (through simple logic and observation of others). In time, I hope that it will no longer be necessary to remind people of rules and stickies, and that ignorance will be driven to naught. Many have been smote by scammers and from that point on have learned to be more cautious.
If you see a locked thread, typically it means a discontinued service. If you see a self-moderated thread, you exercise caution. In both cases you should check the OP's trust and reputation on the forum.
I see no point in preventing access from locked/self-moderated threads for people who actually wish to control real trolling/spamming/etc on their threads.
