Yet, you don't get to choose a Apple laptop with an AMD instead of and Intel processor, a Samsung handheld computer with an A7 processor instead of a Exanos or Qualcomm. In life, things come in sub-optimal bundles and you pick your poison.
So there are some limitations. But I still get to make a choice for every single purchase. I don't have to select just one company and then have that company provide every single piece of computer equipment that I get all year.
The problem is that we often only have a few choices even in a commodity market because of economies of scale. The economics of spending billions of dollars to develop high performances CPUs have dwindled the field to a majority player and a consolation player. Likewise, in the US, there aren't an excess political resources to fund billion dollar campaigns where only 1 person wins, so there is only about 1.1 political parties. When you scale things back you get more diversity, (e.g., local politics or SoC chips), but at the top of the food chain, it's not much freedom and not much service...
I think you misunderstood the 1.1. In America we get to choose 1 president for 4 years, 2 senators for 6 years each, and 1 representative for 2 years. That gives us 11 votes over 12 years. Yikes, my math was wrong and it's worse than I said. We get less than one vote per year.
I care about more than 11 issues, but I don't get to choose 11 different politicians to address them - or even 3 different politicians to address them.
I own more than 11 different electronic devices, and I can choose a different company to provide each device.
