You can make VAT progressive again, e.g. by issuing flat or income-based refunds. Also, I don't see how enforcing VAT requires abolishion of cash, considering that most of Europe has 20%+ VAT rates on top of large income tax, and cash is, if anything, more popular in most European countries than it is in the US.
