But let's be clear, you've essentially used this fallacy (not to mention the appeal to emotion) to support/base your point: https://en.wikipedia.org/wiki/No_true_Scotsman
I.e. "True slavery means that police/authorities won't intervene". It shows that you don't have a well-defined definition of slavery, or are using one that is too-constrained to the generally-accepted definition of slave/slavery. Here are a few:
[...]a person who is the legal property of another and is forced to obey them.
[...]a person who works very hard without proper remuneration or appreciation.
[...]a person who is excessively dependent upon or controlled by something.
