I do not believe that regulation will cover that we all have to declare exactly how much Bitcoins we each own.
Right. You only have to declare how much bitcoins you have if you need to pay your taxes from the amount of bitcoins you sold (this depends on the country you live in because not all countries tax bitcoin). In my country our government regulates the bitcoin exchanges here for more than a year now but we there's no statement about taxing bitcoin. With regulation this can help stop users who plan to use the coins for doing shady,illegal,scammy things like trading drugs guns etc.
yes its true and i agree with what you are trying to point out, and besides it doesn't mean that this might be a hindrance and i don't think it so too. declaring your asset would also be a risk but could also be for your benefit, not because they will be the ones monitoring each and every transaction you will do but for some reasons you have said it would be much wiser than being accused by false statements right? because it might come to the point that they might accuse you, hopefully not.
