If we have land we are not a burden on others

We will not (be allowed to) become a burden on others if we are prevented from selling land such that after doing so we would have insufficient to live independently.

It should be impossible to sell land such that by doing so, we would have an insufficient amount to live independently, the reason for this rule would be to prevent people from becoming a burden on others. We should be able to sell our land only if we have enough remaining to live freely and independently.
