Every form of currency suffers this problem in the beginning.

There are really only two ways around it: easy convertibility into another currency that people already understand, or direct use-value of the currency commodity itself.

It's a question of social inertia. It's too early to expect people to think in BTC.

Logically speaking it doesn't make bitcoin a USD proxy, a non-currency or "not-a-economy" as you claimed. Fixing the bitcoin price to another currency is a good solution when the value of 1 bitcoin is changing rapidly, as it would take a lot of work to adjust it daily. Besides, you can fix the price to the average of multiple major currencies (like average of euro, American dollar and the British pound).

A currency can have an economy fully its own and still have prices pegged to another currency. There is a lot of historic precedent for that. You act like its an abhorant practice. Prices will stabalize as the BTC price approaches something more workable on a global scale, like $21,000,000/BTC

Sorry man, IMO it will be years before BTC can function in the way that you want it to. First you need widespread adoption.
