I think it's the other way around. If you need a visa to enter, the government considers you more suspicious than those who can enter without a visa. And you will likely face more scrutiny at the border. Some countries have visa-on-arrival schemes, which are the opposite of ESTA and ETIAS. The visa still exists as a formality (maybe due to reciprocity or as a tourist tax), but you need to do little beyond paying the fee to get one.
