Precautions on that or higher levels of expense and complexity, like burner phones, dead drops, networks of couriers, cell and gang org structure are standard procedures in organized crime. Un"organized" single small criminals might have a larger fraction of bad opsec, but they aren't all stupid. A few will be caught by making mistakes, but the rest will learn from that. Criminal methods undergo evolutionary pressure.
