Laws should made from purely utilitarian point of view, not the moral one. The reason why, for example, murder is illegal isn't because it's immoral, but because most people do not want to fall victim to such crime so they voted to make it illegal. Same for theft, or even such minor annoyances like fining someone for playing music too loud.
You are trying to draw a distinction between the "utilitarian" and the "moral". But, to quote the Internet Encyclopedia of Philosophy (IEP), "Utilitarianism is one of the best known and most influential moral theories" [1]. Claims about what is "utilitarian" are inescapably moral claims.
> but because most people do not want to fall victim to such crime so they voted to make it illegal.
In historical terms, that is quite false. In every democratic country, murder was already illegal for centuries (even millennia) before democracy was introduced. In fact, the earliest surviving legal text (the Sumerian code of Ur-Nammu, c. 2100–2050 BCE) criminalised murder, and predates the invention of democracy in ancient Athens (594 BCE) by approximately 1500 years.

The issue is that many folks want to view others as $POLITICAL_PARTY first and human second.
Hell, half of conservative political rhetoric is distinguishing between real and fake Americans.
If I point a gun to your head do you think we can stand there and have a calm and rational discussion about whether I should pull the trigger? Of course not! You're going to fight to protect yourself.
Is there another universe where all the religious people are very pro-economic redistribution? That seems to be within reasonable interpretation of the teachings of Jesus.
