Take e.g. a shared flat: People come and go. A new flatmate should not be responsible for old purchases. Also we should not be forced to create a new Collective everytime the member number/constellation changes (which is currently pretty much the only effective way to deal with this).
This could probably be implemented by adding a join_date to each Membership and calculating each member's share of the Purchases/Liquidations starting from that date only, so that someone joining later will effectively have to pay only what he made use of.
