It's not. Maybe you're thinking of libertarianism? The conservative ethos is to preserve and promote a social hierarchy. This requires both winners and losers.
Limiting the power of government is a central idea in conservative thought, especially in America[0].

I think the fairest thing to say, from that Wikipedia article, is this: "Conservatism in the United States is not a single school of thought." "The history of American conservatism has been marked by tensions and competing ideologies".
Limit government interference in the market? Yes.
Defund the police: Hell no.
Defund the military: Mostly no.
Defund the IRS? Hell yes.
Let anyone who wants to marry get married? Let anyone who wants to have an abortion get an abortion? Go burn in hell.
It really varies depending on the issue.
I would claim that these apparent contradictions all make sense if the goal is to preserve and promote a social hierarchy.
One might wonder how Christianity and capitalism are even compatible. Read what Jesus said about money! Sometimes it appears that most contemporary conservative Christians in the US have not read The New Testament at all, and in some other countries, such as in South America, Christian social movements tend to be (more naturally IMO) explicitly anti-capitalist. I have this strong impression that US conservative Christians have come to believe that the so-called Invisible Hand of the market is actually God sending reward and punishment, which is why it's now ok and even praiseworthy to seek after and accumulate wealth.
- police oversight
- abortion
- welfare
And even on dumber issues like public transit. Say what you will about authoritarianism being the real problem but most people vote and ally themselves based on the progressive-conservative axis.
