Plastics aren’t a system. Some plastics are likely to be manufactured in 100,000 years simply because their made from abundant atoms, non toxic, and have useful properties. The current global economy on the other hand isn’t stable across months let alone hundreds of years. But that doesn’t matter much, the meat your eating today probably didn’t come from a wild animal like the meat your ancestors where eating 100,000 years ago but it’s still edible. Different systems to produce essentially the same thing across vast stretches of time.
