Most people are not you. Do you really expect most people to go through some lengthy process to get BTC? They will go to Circle.com and the like to buy from. Thus using cards the cost is passed to the consumer.
Please be open minded and think about how the average dud will buy BTC.
I went to circle.com, signed in, registered, verified phone. And then circle told me 'At this time, bank accounts and credit cards from your country cannot be linked to Circle. Our apologies for the inconvenience.'
Not much help there for this 'average dud'.
