I think it is not hard to use bitcoin as a regular currency. Because bitcoin is an electronic money and i know that someday it will be known and will be use by many. And bitcoin has no difference with the atm that we have today. Bitcoin is helpful and bitcoin is safe so it can be a regular money currency.
You will be surely true if you said these words 6 months ago ( I mean in the last year ) because currently the fee for the Bitcoin transaction is very high ( about 2-3$ minimum for per transaction which is also depends upon the input and output of the Bitcoin transaction that we made ) .
So here this is really a tough decision whether to make buy or sell things with the 2-3$ extra payment or not because at one side we have the ease to use our money through the internet data and opposite of this we need to pay high fee as the extra spent of our money for the buy of very lower price things .
So currently o don't think you are right . Op is saying true 100% .
But I think in the future it at be possible for the people to make transaction fee free because of the idea of third party Bitcoin wallet where transfer of Bitcoin digit written only not of the actual transfer of Bitcoin ( wallet to wallet of third party ) .But I think we need more for such things because this type of service needed much better support and developer team .
