If folks are found not guilty after spending weeks or months in jail (while being low to medium risk of fleeing), shouldn't we then shoulder the responsibility of fixing the life we've left in shambles? Especially since there was, indeed, other options we could have taken? We don't: At least in Indiana, even if you are found not guilty, you have administrative costs taken out of the bail amount you got back. And that's if you were lucky enough not to be forced to use a bondsman - then you won't get anything back (Yes, folks are court-ordered to use bondsman).
I don't think we should be asking for a surety for low risk at all, and medium risk is iffy - and this is just for felonies. I don't see a good reason to hold anyone for a misdemeanor.
I'm not certain that removing bondsman would make the US system more sane, though it does mean that you aren't charging an actual fee to get out, but instead returning (most of) bail if found not guilty.
