To violate the Lockean proviso means we owe more land rent than we are owed

If we only own a small amount of land then we owe no debt to our neighbours because we have taken (are occupying) no more than is a reasonable amount. The reality that land is not owned, it is borrowed, is not relevant unless we are in occupation of a significant quantity.

No one owns land, we rent it from one another and so the more land that is owned, the greater the rent we owe to our neighbours. If we owe more than we are owed then we can expect to receive a request for payment. Someone with only a small amount of land is owed no less than they owe, so no charge is brought against them. Someone with much land owes a greater quantity of land rent than they are owed so they must pay the discrepancy. To own an excess of land means we owe more land rent than we are due, thus the remainder is due (to be paid) to our neighbours.

To own an excess of property means that we owe more land rent than we are owed.
