You get what you measure. If your metric is claimed completed story points, you'll get people good at claiming story points.

Every system can and will be gamed, either directly or indirectly through osmosis and attrition.

The only way to win is not to play. Put people in charge that know how the pie is made, then trust them to make the right calls.

This btw is one of the major reasons why non-technical founders/managers so often fail.
