It's not scary since the government is always right.
It's not scary since the government should be able to deny free people the right to travel.
It's not scary since people never have family or work obligations outside of the US.
It's not scary since people in debt can always easily afford to pay off their debts and always have their contributions tracked properly.
It's not scary since there is never a slippery slope with the government actions that involve frustrating the rights of a disliked minority.

My philosophy on this is that if a person isn't currently locked up and hasn't been locked up and isn't currently on trial for a criminal offense, then their freedom of movement should not be curtailed by passport denial/revocation. Unfortunately, the government sees it differently than I do on this matter and has since the POTUS was a former Arkansas governor whose biological father ditched him and his mother as he saw it -- that is when this HHS-State passport denial/revocation started and the numbers of denials and revocations started to skyrocket for free US persons.

The amusing thing is that citizens of the US who are denied a US passport or have a valid US one revoked can travel internationally still if they have a non-US passport but that increases the expenses for such persons and probably somewhat undermines their ability or willingness to pay.

I have no doubt that some of the US child support debtors with the largest unpaid debts in TX, NY, FL and CA include some US dual-citizens reported up to HHS and State via HHS.

What is interesting to note is that a few thousand dollars in child support debt results in passport denial/revocation while even millions in civil debts subject to collections processes by the IRS does not ordinarily result in US passport denial/revocation -- the attempt (a handful of years back) to make IRS debts a general basis for US passport revocation/denial got defeated in creative ways.
