Self-mining, franchised mining etc. makes only sense when we can't sell chips anymore. The turnaround time for selling chips is much faster. Every KH/s used for mining instead of selling chips (as long as it's profitable) is a KH/s wasted. I do agree though, that mining is good thing, as it festers independence and a continuing stream of income. But effectively it means less income/dividends.
I agree that selling chips is a way to get the maximum profit up front versus mining that will spread the income out over time. However, in this climate of an escalating USD/BTC exchange rate, mining with the chips eliminates the exchange risk.
If USD/BTC rises to $5000, our bitcoin profit from chip sales will become miniscule, whereas a mining farm will still be happily cranking out the coins.
A balance should be struck between sales and self-mining.
