A law cannot remove a natural right. A law can protect a natural right or oppress people by using violence against them if they exercise their natural right.
One stark example is the Fugitive Slave Act of 1850 in the United States. This law required that escaped slaves, even if they reached free states, be captured and returned to their owners. It went further by mandating that citizens and law enforcement in free states assist in this process, effectively making it illegal to help runaway slaves. Penalties for non-compliance were harsh—fines and imprisonment loomed over anyone who aided a fugitive.
By today’s standards, this is widely seen as abhorrent because it not only upheld slavery but forced people to actively participate in it, stripping away any moral or legal refuge for those seeking freedom. It’s a glaring relic of a time when human beings were legally treated as property, clashing hard with modern values of liberty and equality.
