Average consumers don't care Anonymity so much. Most consumers like to buy stuff from where they can put their trust. In such place, they don't really care give some personal information to the merchants.
I think the bitcoin itself is enough for those privacy paranoia like Satoshi himself. However, if you want to develop some projects, I guess you may want to sacrifice the anonymity nature of the bitcoin, just focus your attention on the speed/reliability/lowcost/safety/convenience/legality.
So I think some centralized service is good for the bitcoin community. and privacy paranoia can just use a Tor proxy while sending and receiving the coins, and not forget to change your address every time.
In that case, why use Bitcoin? Why not use paypal or VISA?
The only value I see in Bitcoin is that the limited supply of the money. And bitcoin just make this money supply limitation idealism into reality.
If Paypal or VISA decide to support bitcoin payment, then of course I will use paypal to store bitcoins!
