This is incorrect. The physical card itself expires every 10 years, but your status as a permanent resident doesn't. That can only be revoked by a legal process.
Obviously if you do not renew the green card itself, you are going to face practical issues, because you have no easy way to prove your permanent resident status. So things like employment verification because of new employment and entering the country from abroad will become quite a bit more difficult.
