SC dont want to make loot easy to get. If it was then players get to TH10, maxed out, more quickly and have no reason to purchase gems. On the flip side they dont want players to simply stop playing out of boredom or finding loot to hard to get. It ends up being a job to find the balance. A recent example of this would be the introduction of elixir for walls. It clearly took a lot of Elixir out of the Clash economy, and perhaps made some players just stop playing. So they tweaked how you can use Elixir on walls and I have no doubt they will monitor the effect and if they need to make a further change.
The thing is, SC have all the data they need to show what is truly happening, how much loot is in the Clash economy, how many times players hit next, how many players are active, and so on. They would be able to assess the impact of the suggestion here, and if they thought it viable I'm sure they would try it. My thinking though is that it wouldn't work, and many players would just learn how to exploit it for a free shield, the game has too many ways to dump or hide loot if you really want to. I just finished a session, built up 3m gold, 2.5m elixir, then spent the lot, leaving empty storages.
