So yes, it's dangerous. But it's very cheap, and poverty is far more dangerous than asbestos. It's simply a fact: residents of most countries simply can't afford a 200k dollars asbestos-free house, like Americans or Europeans can.
If Americans had less affordable homes like the rest of the world have, they would still be building them out of asbestos.
https://aiobs.org/how-healthy-and-costly-are-the-most-used-i... shows insulation cost for a (typical?) 1500sqft (~140m^2 for the rest of the world) home. The most common, and also the cheapest, type of insulation being fiberglass bats at $560. So if this home would cost $200k, that's 3% of the total price. So even if asbestos would be free, it would barely move the needle in total cost.
Edit: That $560 looks suspiciously low. Googling around some more shows an insulation (incl. installation) cost for a "typical" home at around $3500-$4500. In any case, a small fraction of the total cost of a house project.

Sure it's not good for you, so using PPE is certainly warranted, but it's on a whole different level of badness compared to asbestos.
[1] Per wikipedia, there are some varieties of mineral wool used for high temperatures (think insulating industrial furnaces and such) which are carcinogens.
