Explanation:

Elasticity refers to the change in the consumer's demand or the supplier's ability to produce depending on the change in the price of a commodity or the income.

When the demand is elastic, people are able to change or adapt  their demands immediately. So, this means that if the price of a commodity will be increased, the people will not purchase that much on that commodity. This will then affect the total revenue of the company. Due to low demand for the product, the total revenue will decrease.

you did not attach the discourse, but i assume it to be the discourse on the origin and basis of inequality among men (the original titile in french is: "discours sur l'origine et les fondements de l'inégalité parmi les hommes"), also know as "second discourse". in this discourse, jean-jacques rousseau emphasizes that private property is the basis of all inequalities.

therefore, what enabled the old regime to maintain as long as it did was private property.
