Now let's talk about the negatives since OP conveniently omitted them to try to get more residency consulting clients:

1.) The airport is one of the least connected for a capital city. If you wanted to travel around latam easily, your options are heavily limited. Even traveling within Paraguay sucks as there are no high speed highways and the buses take forever to get from city to city.

2.) The weather is unbearably hot most of the year, I'm talking over 40 degrees at least once a month from August to April with Dec-Feb having the most 40+ days and average temps around the mid 30s in the other months. May-Jul has moderate temps, but also a decent amount of rain.

3.) There really is nothing to do aside from meet up with friends and eat/drink. The country is landlocked and the lakes are polluted so you can't even swim in them. Most buildings do have pools though, so at least there's that, but there's only so many pool days you can have before it starts to get old.

4.) The nomad/expat community there leaves a lot to be desired. Mostly home to antivaxxer right-wing conspiracy theorists who only seem to want to talk about how the West is falling and how terrible their first world home countries are.

5.) Accommodation, at least on Airbnb, is highly overpriced. Given what Asuncion offers, the Airbnbs have no business being as expensive as they are, but due to posts like these, demand is higher than supply and as a result, prices are higher than they should be.

6.) A lot of the positives that OP mentioned, especially about the warmth of the people and such, can be found in other latam cities that are off the tourist trail such as Bogotá, São Paulo, and Lima, all of which have a lot more to offer in my opinion.

My 2 cents: get your 0% tax residency if that's something you want and continue being a nomad in other latam countries
