No, we don't. We need other ppl use Bitcoin as a medium of exchange for goods, not for other currencies.
Go tell that to all the people that want to get some Bitcoin.
Go tell that to all the merchants that want to be able to accept Bitcoin without their accountant getting a heart-attack.
Go make the same stupid comment to the people that are sick of Western Union fees and who just want to send some money to their family.
Of course we need more people to accept Bitcoin and trade it directly for goods and services, but that doesn't mean we don't need a healthier exchange ecosystem with established and solid foundations.
If you do not need such a service than you are free not to use it.
Chill out. Services like urs prevent Bitcoin from world-wide adoption. Of coz this is arguable, u r free to have other opinion.
