If you are not in the US then there's no need to be bothered about whatever is going on in that part of the world. However if you are in the US, then you need to understand the reason why those people you mentioned are filing their returns because without them knowing the implication of not filing I don't see them filing willingly. So, since you are advocating for people to evade the payment of tax then you should also be ready for the liability that could arose from such decision. Wish you the best.
