You seem to believe getting taxed is a choice people make. However, on the one hand economists like Zucman and news stories like the Panama Papers have proven the ultra-wealthy and politicians ("economically useful people") pay way less tax than regular people. And on the other, basically most people disagree with at least
some of the uses of taxation, such as a war spending in the US. In fact, sometimes people get taxed without getting any benefits at all in return, such as during government shutdowns.
I think this all calls into question your basic premise that "politics is downstream of what we humans want", ie that the state is an emanation of the collective will of the people, which it serves. The facts fit equally well, if not better, an interpretation in which the state is independent of society and seeks to extract resources from it. This is also consistent with the Weberian state conception in which the state starts as the "stationary bandit" that collects taxes from a village to protect it from other bandits.
Your conception of "economically useless people" is also incoherent. Economic science is about how to distribute rare resources to maximize utility. These people are no less able to work and no less able to benefit from utility and are therefore not "useless" from an economic standpoint. I think you would benefit from just using words like "rich & powerful" and "poor & weak" which if I understand correctly is what you actually mean.
