> So, in your mind, making a payment, recieving a payment and holding money in savings are always bad when it goes against any government's law or order?

That's not how I read GP; "Why would you want to do an end-run around the government when using currency?" is different to, well, whatever it is you are saying (I'm not sure I can decipher it well enough - seems to be "using currency is bad when it goes against laws", but I think that's fine too, so not really sure what your message is - maybe you can clarify?)

Using legal tender is not a problem. Using barter (which is what using crypocurrencies boils down to) is also not a problem. Lack of reporting your income to the tax authorities is a problem. Most bartering systems are too small to warrant the attention of tax authorities, but cryptocurrencies facilitate bartering at scale, which does warrant interest.
