"a set of laws instituted by the Athenian lawmaker Solon (c. 638 BC–558 BC) in order to rectify the widespread serfdom and slavery that had run rampant in Athens by the 6th century BC, by debt relief."
"The seisachtheia laws immediately cancelled all outstanding debts, retroactively emancipated all previously enslaved debtors, reinstated all confiscated serf property to the hektemoroi, and forbade the use of personal freedom as collateral in all future debts. The laws instituted a ceiling to maximum property size - regardless of the legality of its acquisition (i.e. by marriage), meant to prevent excessive accumulation of land by powerful families."
The value is such that no one could normally buy the infrastructure, yet such infrastructure is often sold for pennies.
Obviously people who are potential bidders in a market are heavily incentivized to downplay the value of what they're bidding on, so it's not clear to me why their metric of valuation should be privileged above all others. It's just like the idea that efficiency should be conceived of in terms of minimizing production cost, without regard to the effects of that approach on customer/employee retention or organizational resilience - partly because those second-order effects are a little harder to measure, partly because owners have an economic incentive to promote that particular definition above all others.
