It's only easy if sheep download and run the software, which paradoxically runs against the Bitcoin ethos, therefore making it many orders of magnitude more difficult to destroy.
The biggest risk is mining centralization. Mining costs are denominated in fiat terms. Which means they will have a fiat like mentality and will sacrifice the future if it means surviving now. (Accepting spam transactions/fees for a greater return per block)
I would willingly run a Bitaxe at home to participate for free. I don't care if I would be losing by doing so. I would view it as a payment for securing the network and make it more decentralized. There is a Bitaxe on Amazon for less than $100 and I am planing to buy one. It would be nice to find a block, but that would not be the reason why I would have done it.
More, or rather all people using Bitcoin shell buy one. One million times 1TH/s is already a dent and a difference.
