AA Group: What is the significance of the language of "private property rights" re: slavery?

[MedusaX]

1. Private Property Rights provided a Constitutional loophole in favor of slave owners...

states which did not allow slavery
were faced with having to allow slave owners, from other states, access to former slaves who had escaped.... because of 'property rights'

Slave owners used 'property rights' to fight against abolition by demanding that the government compensate them for the 'taking' of their property if slavery was abolished.

Slavery was big business.. 'property rights' protected the enforcement of contractual agreements associated with the purchase/sale of slaves.

'Property Rights' also eliminated any legal action /criminal charges for physical abuse or killing of slaves since there was no law against destroying ones own 'property'.

'Property Rights' also prevented the possibility of a federal tax being levied on slave owners for having slaves.... because that would be considered a 'property tax' which was a state power.
