At what point should you consider mining to support your own bitcoin investment?

Recently I've started to think about buying an ASIC miner, not as an investment, but simply to support the network and help protect the bitcoins I already own.
Is this logical even if I only cover my costs?

I think if you can afford it and rationalize it as paying for itself as security as opposed to mining out put, I think this is a good plan.

I use this sort of rational whenever I spend BTC.  I'm supporting the system which, in turn, makes my own investment actually become worth more.
