But there is no point in answering that 2 "questions", because the assumption behind this 2 "question" is, that EU-countries have to give up there social model, if they do not agree to some imaginary edict and that doesn't make any sense at all.
Thanks for proving that in your case I am correct about the European psychosis.
You think that you can have an unsustainable tax and redistribute economic model and not have to confiscate the wealth. Duh.
And therefor you assume implicitly that a non-compliant Bitcoin won't be used to hide wealth.
Look your economies are going to implode. And the retirees are going to support the government to find taxes where ever they can.
You are just ignoring the fact that the USA has major economic problems without a social system, there was a world wide crisis which affected most countries including the USA and it had nothing to do with any social system.
