Let's say you've been earning coins from signature campaigns for years and now these amounts are on the 6 figures and you want to spend some of it in things because otherwise is just an useless number on a screen.
The moment you want to spend these coins, you have a problem if some of them are blacklisted in some of these chain analysis programs, and most services have or will have these services in place by law eventually, which means you have all that money stuck doing nothing, unless you want to spend it on cheap stuff where it could be purchased anonymously online and only on p2p purchases basically. So this limits all that money to basically irrelevance since most people already has fiat to spend on these small purchases and paying with a bill is easier and more private than having your transaction in a blockchain record for life.
But, what I am saying above, is that since the only way for them to control Bitcoin is to apply unfair legislation, they can use the media you refer to in order to block every satoshi that you own.
It doesn't matter where it comes from, but since it's not bought from their whitelisted exchanges, then it's illegal for them.
You can believe taxes are theft, or that these blacklisting programs are bullshit and unfair which I agree, but that doesn't matter because the consequences are not desirable, so you want to be aware of these things. As it stands Bitcoin implies this risk when paying for things.
I do believe that, but I suggested doing things transparently if it suits you most.
It depends on many things (the country you live in, your age, your financial goals and current situation), but you can just declare the bitcoin you own and the bitcoin you earn and you 'll gain your missing peace of mind.
Again, I never suggested and never will suggest to avoid taxes or break the law.
So in this context, it doesn't feel that comfortable paying for things unless the coins you have come from basically a regulated exchange, which limits the Bitcoin economy.
That's exactly what they wanna do. That's exactly what they want to make us believe. And, to be honest, although I disagree, I can respect that it worries you, because their brain-washing abilities are top-notch and nobody can deny that.
