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.)
