I think the idea to reset the TestNet chain is a good one but it shouldn't take place every block because that would make it a nightmare to use. You need a working chain to form and grow. Not to mention that the coinbase rewards need to mature for 100 blocks before they can be spent. But I don't think there is any easy way to implement it so that it happens automatically and without human intervention. Lets say we decide to reset the chain every 4032 blocks (2 difficulty adjustment period that should take 4 weeks assuming normal hashrate). The problem is the genesis block. How should be build that? We certainly can't predict the future hash of a mainnet block to be used in it and by that time this future block may not have been mined yet. I don't think those who redirect their ASICs to testnet care about money or securing the main-chain.
