People should never be considered property or money. This should be able to be agreed upon by everyone. Even if that was part of the culture doe snot mean that it was right. Racism is part of our culture, that does not make it right.
Why should it be agreed by everyone? It clearly isn't even today as there are a number of cultures that still consider people as property or money and with none of the mitigating laws that the Israelites had.
I still think you are reading modern thinking into ancient worlds. Based on the few verses covered so far, it is far from clear that the Israelites were ever considered property or money. Even women's bride price indicated that they had value, not that they were property.
I'm glad you think racism is wrong, but a hundred years ago it would have been quite acceptable and normal. In some countries this would have resulted in persecution (USA, Germany for example) and that would have been considered right at the time.
Apart from the problem of moral objectivity only being possible if there is some objective moral giver, you are missing the point of this discussion on the issue of slavery in the Old Testament law. "The past is another country; they do things differently there." (Hartley).
Their system worked for them, whether we liked it or not.
You can get all indignant about the fact that slaves could be sold, but would be quite happy that whole families starved to death because of debts and failures?
You can get all indignant about the fact that slaves could be beaten, but miss the point that there is a law that implies that this is not a good activity (and that is just in the few verses we have covered).
Would you be complaining if these law wasn't there at all? Would you even consider it? The fact that there is a law means that they did consider it and tried to find a solution that provided that people would not starve nor be out of pocket for someone else's failings (check out the laws on oxen goring for example).
The bulk of the non-ceremonial laws relate to social justice, they just went about it in a different way from what we would (and who is to say that our way is better - racism in the US still exists despite the Civil Rights movement and the current popular solution - Critical Race Theory - just transfers the racism to someone else so I don't see it disappearing any time soon).
The Bible uses the term 'Shalom'. Most people think it just means peace, but it is far more encompassing than that. A better term might be 'wellbeing', but also 'restoring the Status Quo'. When you look at the OT laws through that lens there is a clear tendency towards restoration - including restoration of freedom in this case - nobody should feel short-changed or resentful, because that leads to escalation (and we have seen that in the race riots of a year ago, riots that didn't solve anything because they just continued the resentment).
In conclusion: Don't assume that a law dealing with the death of a servant/slave somehow means it was normal behaviour. Clearly it isn't (if the slave could love his master or the fact that he was answerable for the death). Whatever we think about slavery now doesn't change what they thought then. The laws in general indicate that it was not a good thing for Israelites to go into slavery, but rather that it was a necessity to ensure survival. There are probably plenty of people in the third world who would indenture themselves for 7 years if they were guaranteed food and shelter for themselves and their families.
