It's the only (that I know of) way to avoid tax evasion and paralel economy.

There are incentives (tax deductions) that are granted to citizens who ask for invoices with their fiscal details

It is indeed progressive because it unburdens citizens from a massive yearly headache when submiting taxes. It's progressive because it avoids physical printing of receipts, thus reducing waste and paper consumption. It is progressive because less tax evasion means more taxes to apply in free healthcare and social security.

Having people not dying because they can't afford insurance, or being restful that the state will cover up part of their expenses if they can't work (for eg: if they have a flu and can't work for a week) seems pretty progressive to me and a good tradeoff for leting the government know about a few purchases you make.

Also, if you want go paperless, your bank also knows about all your financial transactions and I don't see people caring too much about it as they care with government...

wow, we went to "we need to do it or people will die" pretty quickly there. XD
