Agreed. Always hated that design pattern. It's so clearly engineered to make people give up and just press agree all. You just got to the article you want to read, the cookie thing comes up, and you sigh deeply. "If I click to 'manage cookies' because I don't want their trackers, I'm going to have to go through another page, deselect 20 checkboxes, click OK and be brought back to the front page where I have to find the article again... Or I could click accept all". And you don't just have to do it once per site - it will reset and get you to go through all that again. It's not so much a choice as a battle of attrition.
You don't always have a choice without regulation. You may be in charge of the safety of the car you buy, but not the one your neighbour buys - or how often he gets it checked by a mechanic. If there's no regulation for any of it, his brake might fall off and the car will smash right into someone you care about or yourself
I'm sure you also agree with there being a speed limit even though could also argue that people just should not drive faster than a sensible speed and that could be their own judgment rather than a law.
And as you point out, it has to fit within your budget. Making car safety an expected standard rather than an up-sell significantly lowers the barrier of entry for safety, both in terms of economy of scale and in terms of the incentive for market differentiation of a luxury and a budget brand being shifted. - Setting minimal standards often lowers the cost for everyone. Medicine is a good example; The US is one of the countries (the country?) with the highest cost of medicine. Sweden considers it a right that people can get the medicine they need and it is to a great extend covered by the government. All medication is significantly cheaper there. - And I'm not talking about the price to the customer here - I am talking about the full price, including the part covered by the government. Because there's much better bargaining power with the sellers, and you can buy in bulk. Furthermore there's not a doctor in the mix who gets a commission on the sale and wants to get you to buy the more expensive brand that's the exact same as the cheaper alternative in terms of the chemical makeup.
All in all, where you put the boundary isn't cut in stone. But I'm sure we can agree that some regulation, minor or major, is a good thing.
Regarding your other paragraph I don't have much to say, really
