Well sure who doesn't like more money, but how is this gonna help the current game economy problems?
What would be smart is to allow people to stake cards against the land to earn more of the SPS pie.
This solves the problem of oversupply of cards, and gives older cards more utility as it could be the amount of staked CP that actually matters.
With cards being staked, there will be more pushing and shoving and potentially more packs will sell as people scramble for more cards.
I know this is all coming later, but a simple card staking system (perhaps we could use the existing delegation system somehow) would benefit the whole eco-system as a whole.
