What I got is that he's implying that it's not needed because they keep on printing money to fund to so called infrastructures and other Government services.
President Nayib is right. Taxation was invented when some form of gold standard existed, before national currencies could be produced at will by Govs and Central Banks.
The only way for the gov to finance their expenses was to get money from their citizens - or from abroad, through international agreements, international trade, war, colonialism etc...
With the abolition of the gold standard and the introduction of fiat currencies produced at will, taxation becomes unnecessary.
We can discuss whether it is better with taxation or without taxation.
I'm not saying that taxation is bad. Maybe it is better to keep it.
I'm just saying it isn't necessary - within a fiat currencies system.
Pres. Nayib is 100%
