You asked

what social or economic conditions made a law like this necessary for ancient israelites?

The passage, plainly, with room to sit with it.

Leviticus 25:10

“You shall make the fiftieth year holy, and proclaim liberty throughout the land to all its inhabitants. It shall be a Jubilee to you; and you shall return every man to his possession, and you shall return every man to his family.”

This verse is part of a longer section in Leviticus, a book of laws and rituals given to the Israelites after their exodus from Egypt. It describes the regulations for the Jubilee year, a unique social and economic reset that was to occur every fifty years.

What does 'liberty' mean for a society, beyond individual freedom, when it comes to economic and social structures?
