The question confuses obligation with consequence.
Also, eliminating cash bail (the requirement for up-front payment of cash for release on bail) doesn't necessarily have any impact on the penalties for violating bail. (While the federal system retains cash bail as an option, it doesn’t have the regulated minimum percent of the bail penalty as an up-front payment system feature that most state systems have in one form or another, and its quite possible to have 0% cash bail in a situation with a specified money bail penalty, and—aside from occasionally producing confused public commentary when people unfamiliar with the federal system read news about a case like that—it works fine.)
That’s it, same as if a bounty hunter comes for you due to cash bail and a bail bondsman. That dance is an unnecessary private industry Rube Goldberg contraption when you already have a judiciary who can determine boolean bail and law enforcement for retrieval.
(extended family works for a bondsman in a Midwest state, familiar with the system)
The bounty hunter isn't going to collect any money since there was no cash bail involved...so we don't even get that anymore. No one cares anymore if you don't come back for your court date, you just go somewhere else and even when you are re-arrested for some other crime, they simply don't care.
The only point that I made here is that without cash bail, there are simply no bounty hunters to consider at all. They don't exist, because there is no economic basis for their existence.
How we get people to appear for their court date when they have no reason to, is another story all together, and I have no idea. Obviously, someone living unhoused in society without assets to freeze or a home to confiscate, doesn't have much reason to show up. They are also the ones that couldn't pay bail anyways.
Does it really work like that in the US? You don't get judged in abstentia? Also, suspended sentences aren't automatically unsuspended if you get arrested a second time for similar crimes? I thought suspended sentences were a big thing in modern countries.
It is usually just petty crime, and even if they make a judgment, they are just happy enough that the person is now some other jurisdictions problem. So let's say you have a warrant in Sitka Alaska, but in the mean time you've moved to Seattle, Sitka is like "this guy is Seattle's problem now, whatever we decide here we aren't going to pay to have them sent back." They won't hold a trial in abstentia, they'll just issue a bench warrant and move on to the next case.
All bets are off if you make it to a federal offense (e.g. stealing USPS mail). The feds don't mess around.
Getting arrested (again) with an open warrant used to be a big deal. Now at least in King County WA...plenty of people are getting arrested with warrants already out because they didn't appear in court (usually in another state that isn't interested in extraditing)...and they are simply being released again with a new court date. It is a bit ridiculous.
