the charges ,if you might be referring them to as taxes  that the government takes then you might be contradicting your own words of positively impacting the economy, how can a country run when more and more people have a way of transaction that doesn't provide the government  with incomes , I mean I am not saying that taxes are always good but they are sort of primary income for the government and they are a must for running  any nation .

now about business accepting bitcoins it would certainly be a boost for the crypto but at the same time isn't microtransaction for daily spending too much time consuming , people would have to be educated enough to understand the working of the crypto currency and that the transaction process may take time , people would have to be more patient and have basic knowledge about transaction made via blockchain technology , its easy to start accepting bitcoins for mode of payment but people should also use it as a currency , people think of bitcoins more as an asset than a currency  and the volatile nature of the value of BTC also forces them to think the same.
