A thought occured to me today.  For the most part, actual goods have to be purchased somewhere along the line in some sort of national currency.  That is to say, even those who do business in bitcoins, at least have to buy raw materials in dollars/euros etc at the moment, and probably will for quite some time.  This automatically leads to a trade deficit between the bitcoin community, and the various national currencies.   For the time being, lots of people have been wanting to join, and have been buying bitcoins for national currency, this has more than equaled any deficit due to spending bitcoins on other things, as evidenced by the sharp increase in value.  Eventually this will level off.  In order for this not to become a problem in the long run, there would have to be goods/services that could only be (or at the very least are much better to be) purchased in bitcoins, forcing people to exchange fiat currency for bitcoins and closing the trade deficit.  Maybe this isn't a problem at all, once the bitcoin community becomes big enough a large enough number of people will prefer to store their wealth that way that when they are paid in FRN they will exchange that to bitcoin?

I think there already are plenty of goods you can buy only using Bitcoin, they just aren’t mainstream enough to make a big impact. If governments do start using crypto I don’t think we need to worry about the “trade deficit” as you put it. Clearly there will be plenty more demand than supply if adoption continues, and Bitcoin was designed that way.

Bitcoin's current dependency on national currencies for goods and services does create an interesting dynamic. The shift you mentioned, where people prefer to store their wealth in Bitcoin and use it for everyday transactions, could be a natural evolution. It might take time, but as Bitcoin's adoption grows, we might see a shift towards a more balanced trade situation.

There is no easy solution for that trade deficit and I'm quite sure that in current times people still prefer fiat over Bitcoin for purchasing of goods at local stores or in online stores. There aren't any good online markets where users can get unique items only using Bitcoin and that's not going to change anytime soon. Bitcoin is getting accepted by many new people and it will continue to get accepted by even more people overtime, and there are chances that in future some websites or a local businesses might accept Bitcoin only payments for some specific items.

But, still I don't think that any reputed businesses would take a step like that because disqualifying fiat payments could reduce the number of customers for those businesses and that's why any business or site would probably take a route where they will have both Bitcoin and fiat as way of payment. They can instead have a strategy in which users that pay via Bitcoin get some extra perks, bonuses, and discounts, and a strategy like that might increase the trades with Bitcoin but still that approach will take a lot of time.
