Are you sure they get oil changes. I've ran into a few rental cars that didn't even get basic things like windshield wipers. I can't imagine a lot of those companies would take them out of service to change the oil on time.
A little bit of fun trivia for you: state police were first founded to suppress unions and labor through violent means. Using Pinkertons caused backlash, so they integrated the Pinkertons into the government to give it legitimacy.
The role of the police in upholding and defending capital is a well understood mechanic of capitalism. It's either naive or disingenuous or hold that they are separate unrelated phenomena when literally centuries of experience and scholarship demonstrates how they are interconnected mutually reinforcing social structures.
In this case we don't need to generalize across all systems that can be called capitalism, we have a specific instance in front of us to reason about. In the american system and its precursors, the role of the police is clear and well attested.
And people's personal property is not normally capital in the sense of capitalism, it not generally being the means of production or of reproducing capital itself. This is a really basic point which has me thinking we disagree on the fundamental terminology. Capitalism isn't a synonym for commerce, assets are not necessarily capital.
Despite being called capitalist, as a resident of the States that regularly visits other countries. I think many countries are more capitalist than the US, the US just gets called capitalist because we have fucked up healthcare and social services systems which themselves in the US to me seem like taking the worst aspects of socialism and combining them with the worst aspects of capitalism.
The private market would just require people to be more responsible about taking out loans. If people that take out loans for basket weaving often don't pay them back nobody would give out a loan for basket weaving. If someone is on their 5th major or college without completing any credit they won't get any more loans without having some backing.
We are talking about 18-year-old kids with no assets and likely no income, who have potentially never had a job, asking to borrow thousands of dollars because they believe (but cannot prove) that they will graduate college several years from now and make enough money to pay it back. Any banker who would give them a loan on normal terms would be an idiot.
The only reason this works is that student loan terms are uniquely different from the terms for other loans. That is what makes the risk acceptable to lenders. Change that, and guess what -- nobody gets loans.
Do you think government could actually keep up with technology to regulate it? And if they did regulate it would it actually help people or the companies that are buying them?
Not really. Drivers have the choice if they want to drive or not. If it is busy at certain times and rates are lower than don't drive at that time. If you don't want to have urban cores flooded with rideshare drivers find a way to improve busing or other competition in that space.
There's around 4.9k lines of python code and 15.9k lines of patches. That doesn't seem that hard to scrutinize. From a threat model point of view you should be more worried about supply chain attacks from all the third party programs/libraries you have installed on your computer.
