I am not understanding why single payer would be bad

ObamaCare practically didn't even started yet, and you run into headlines like this:

CBO Confirms: ObamaCare Discourages Work

the way I see it:

1) I want healthcare and pay for it already

2) Their be more "choice" in which doctors you can see since virtually all of them would enroll in the single payer system

3) Giving everyone preventive care early will save us millions in not having to treat them for cancer and other expensive illnesses

4) the single payer system wouldn't drop you for "pre-existing conditions" or any other nonsense they make up at the time like private insurers can

5) I would rather pay into a pool that helps other people in need rather than further enrich immoral millionaires that run the current insurance companies

what about any of these are bad and what would be so bad about single payer?

I would tend to agree, IF the system was NOT one devised by the current crop of Democrats and Repubs.
