Second exit

Taxes are paid because they are necessary and it is because they are necessary that they are paid

That is, until someone dares to discuss —to think about— one of them —that of the parallels— and discovers the new hyperbolic or elliptic geometries. Then, if you don't accept that axiomatic or fundamentalist explanation (it is from this or that indisputable foundation that everything else follows), you keep asking yourself:

Why does the Public Administration proclaim itself to be the only possible provider, or the best provider, of certain goods and services?

You can answer this question as simply as "just because", because it can't be any other way. Let's see: if everyone everywhere has accepted it this way; if it has always been this way for as long as we can remember and, where memory ends, as far back as the oldest historical records remind us, —I repeat: if it has always been this way— am I now going to come along and discover gunpowder? Well, no:

Taxes have to be paid because taxes have to be paid. There is no other way. End of explanation.

And if this (overwhelming) argument already comforts you, then you exit the trilemma by the second way out. You are then accepting a circular explanation according to which

"taxes are paid because it is necessary to pay them" and "it is because it is necessary to pay them that taxes are paid".

A loopy "just because" as (scarcely or extremely satisfactory) as

"the rabbit's ears are longer so that it can listen better" and that "it is because the rabbit has longer ears that it can hear better"

—functional explanation philosophers call it, trying to avoid acknowledging its circularity.
