That makes no sense. People can enslave others without any "government" being involved, and they have done so for thousands of years. The people enslaving the others just need bigger weapons so the slaves cannot revolt.

Government can prevent people from being enslaved. But without a government being involved, slavery will still happen. In fact, it will happen much more often as is evidenced by the fact that modern day slavery happens primarily in countries where governments are not powerful enough to stop it.
