Anyone saying something like that clearly has absolutely no clue or concept what the counter-party risks of doing so are nor how bureaucracies actually work in practice. Just promoting that kind of narrative is fundamentally deceitful because its outcomes pose such harm to not only yourself but everyone else you've enrolled in the process.
You'd wake up one day and not be able to get your money. The account would be frozen, they'd refer you to some other department, who would then point back to the first department in a circle. No escalation route, 8 hours getting through to 1 department, another few days, your back in a loop no resolution. In the meantime funds are still going into your account but they can't be removed.
You'd say that will never happen, but this type of finger pointing happens all the time in business and bureaucracies alike. There is a fundamental lowest common denominator, and in a state funded systems that denominator is ultimately negative production value. Business can't afford it, but government gets paid by the money printer (stealing value from those holding the currency over time).
That's not even going into what they'll use your banking information for? We see you deposited and withdrew cash in 200+ dollar amounts multiple times over the span of a year. This is structuring, in addition to your reported income you owe taxes on the undeclared amounts and this has been referred to department X for further investigation, they make a finding and take your money first, wait time for their due process before returning (if you can prove its yours) or just keeping the money (in the case of non-responsive/lost mail). Civil Asset Forfeiture 2.0. Nevermind you do group grocery shopping on behalf of someone else (elderly who can't drive), or other plausible explanations, you are guilty until innocent because they have your money and you lack the power to stop them.
