I think the point being made is about banned by your region's major payment processing corporations, not specifically Visa or Mastercard.
Any statement about a "majority of the world" would need to apply to India, China, and the African continent to be true. In China being banned from Alipay or similar would presumably have the same or even worse effect. India's attempt to go cashless some years back disproportionately affected those without plastic or digital payment cards, further emphasizing the point.
I don't know too much about payment systems in Africa but my understanding is that mobile payment services have been heavily adopted and if a major payment corporation in the region banned an individual it would have a drastic negative effect on their livelihood. If corporate-issued payment devices are easy to do without in Europe it would seem to be the exception, not the rule.
