Would it rather be that one would submit work without having Plagiarism detected simply because of perceived distrust? I think since we have a lot of flow of information online, and abuse of original work is prone to happen, it is only fair that work is detected for plagiarism routinely as standard procedure.

I'm inclined to agree here. Social learning is embedded in traditionalism which can be inflexible at times. The world is changing and we need to change accordingly
