Vote splitting.
800 people may have good ideas but if they all split the vote the wrong person will get in.
As well, it would be chaos on election night having to count ballots and check numbers for 800 candidates.
Sometimes more isn't better. 1 party on the left or right is better than 800 candidates with similar opinions.
In a FPTP system, that's true, but, if we make it true proportional representation, that problem goes away.
While, in our current system, I agree that 1 party on the left and 1 party on the right is better (a selfish view since I lean pretty strongly toward the left and it would ensure my desired policies would be more likely to win out), it creates traps which force people into positions they might not agree with. For example (and none of these are my political views), say I'm a fiscal conservative, but, broadly in favour of LGBTQ+ rights, immigration, etc. Or let's say the opposite, imagine I'm a very hardcore economic socialist, but want strict immigration enforcement and am extremely religious. Or, to make it more relevant to this board, will vote for whoever pledges the most money for transit and promises to build it quickly, and don't really care about anything else. Who do I vote for? No matter the choice, I'm compromising. This breeds discontent and disillusionment with the political system, especially in our world where every position can be recalled and scrutinized. It's better for the country as a whole, imho, to get broad consensus on the policies we want to move forward with.
The ballot counting I'm not worried about. Even if counting the ballots takes weeks, who cares? Is the speed of getting the results really that important? The votes are already cast we're just counting what they are, I don't know why there should be any chaos. It would probably be better as there would be no need for political junkies to stay up late into the night to find out who won.
