If you have valid PR status or a Canadian passport, you can travel to Canada. The "gaming" goes on to obtain / retain either of these two things. But once you have it, whether or not there is an eTA system makes no difference to your ability to travel.
By requiring eTAs from all foreigners, they are forcing PRs to declare themselves as such (and provide documentation that is transmitted to a government database) thus creating a record linked to their PR card # that they entered the country. This curtails some avenues of residency fraud by making it easier for the government to cross-reference the entry to Canada to a specific PR than if they had simply entered on their foreign passport.
