> 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.

Not paying taxes and not declaring your assets is always bad, yes.
