I'm gonna try to play devil's advocate.
Of course it is a choice, it is the citizen's obligation to demand that the candidate they elect will create the governance structure that allows the citizen to have additional choice in other aspects of society, not just the election. No one is forcing anyone to be a slave explicitly or implicitly. The citizen has the choice wheather to challenge the status quo or not, and accept the consequences of that choice.
The citizens cannot make the informed choice and it is impossible for politicians to be informed.
In our jobs and day-to-day life, we all specialize in some kind of knowledge and field. Beyond that, we are ignorant, so to speak.
I don't know medicine or how to build houses. I just know how to make website.
The knowledge of humanity is distributed. The bigger the population, the more knowledge you can store in our civilization. However, our civilization becomes far more complex than for any puny human beings to understand.
I was talking about this with a friend recently. We basically said for a society to survive it must be able to deal with information about the environment, relating to problems that threaten that societies existence.
As the problems become more complex and varied, requiring individuals to become more specialized and orientated to specific problems, then the ability to transfer information between sectors of the society will become less. Now this by itself is not an issue, it becomes an issue when information about an external problem can not be disseminated to those who face danger from the threat. So far this is only relevant to external problems, not political.
We postulated that one reason political threats occur, threats that arise from agents within the society, is because there is not something that links the welfare of all agents within society to each other, we defined "link" as what is felt by me is felt by you and vice versa. This is apparent in all ideologies;
capitalism -> basically a free for all, theres no link between those with capital and those without.
communism -> theres no link between the people who do something for the collective and those who don't.
It is just a fact of human nature, a fundamental deficiency of human intelligence. At this point in the discussion we think; "Given the way the world is, how do you link the welfare of all agents in a society?" So we said how should a internal political threat be dealt with?
Using the logic outlined above this meant that all agents within a society would need to have a understanding about relevant political threats. Now this becomes impossible if the information related to these threats can not be distributed and processed by all agents. This is where I put your statement.
Now what about external-political threats? Lets imagine that there is an external threat of some sought. This threat is so complex that it requires a small group of individuals to develop amazing capabilities to handle and understand this threat. These methods are beyond the reach of any individual outside of this small group. This threat is going to destroy a significant part of society, including these individuals, but this threat is a conscious entity, a god of some sort, and if the small group co-operates with this god, they will survive but a larger part of society will be destroyed. Now what would happen if the welfare of all agents within the society were "linked"? Or what would happen in a society with agents that could transfer and process more information, thereby spreading information about the "god threat" and "political threat"?
To me this demonstrates two ways to mitigate this risk: an increased welfare linkage between individuals or/and agents transfer and process more information. Simply more empathy and greater education, by force/mandatory.
So the premise of your argument is that there are so many problems faced by civilization, that it is impossible for politicians to make the right decision and consequently citizens?
Why do politicians need to know about all problems? We don't need some pseudo-oracles, we only need to gauge the intentions of other agents as humans generally lack empathy. Once you gauge the intention of agents that problems are delegated to, then you need to gauge the skill. And then you need an ongoing structure to manage both, i.e transparency and accountability.
