This is a rhetorical sleight of hand; almost everyone pays FICA taxes at some point in their life, and of course there are other taxes than Federal income tax.
Is it? The article is exclusively about federal income tax - spefically the variable part that you have to calculate yourself, not the constant % that's automatically withheld from your paycheck (FICA).
A large majority have to file though, even if they don't owe any taxes. It's still a pain in the ass.
Unfortunately, the IRS built DirectFile to enable free filing and the current admin killed it. Maybe we’ll get it back in three years after regime change.
