What the parent to your comment means is that video games is serving a purpose such that you cant just "stop." You have to figure out what purpose its serving and find another way of achieving that. A better version of what they're trying to say is telling an alcoholic to "just stop drinking." Yes, if they can do that it would be good advice, but the problem is that they cant stop. So, ultimately that advice doesn't lead to results.
I wasn't meaning to stop cold turkey, there is a whole process to quitting addiction. Sometimes people need to be pointed at what is causing the issue and then help on how to get out of it.
Someone using the term "vicious cycle" doesn't need help naming the problem. They need strategies and tactics.
I don't know this persons case but some of the people I knew really needed the problem stated for them to truly acknowledge it. My close friend had a video game addiction and refused to see it as a problem.
Many people claim that there is no such thing as too much gaming or gaming addiction or gaming issue.
