Western Europe doesn't have bail bonds, and seems to function quite well. People don't run away, because running away from a criminal prosecution means your current life (house, possessions, career, friends, family, etc) is over. People who actually are flight risks (due to the nature of the crime, extensive assets out-of-country, etc) can be held in jail pending trial, but that's pretty rare. OR consider it this way…
Western Europe barely works. Bringing one data point: my ex landlord wasn't really the owner of the house and was scamming rich landlords who had too many properties to control them properly. He also scammed tenants (eg. Not returning deposits). The London metropolitan police jailed him, plenty of evidence and testimonies. He was released nonetheless, he escaped to Dubai (where he has family), he came back to the UK…
The problem is that bail really doesn't work better than a lot of other sorts of interventions. Know what has a good track record? Letting folks go and having them check in regularly. Calling them to remind them of appointments and court dates. And this has the added benefit of not ruining innocent people's lives and it is a better use of taxpayer money.
Not forcing ruin on folks really does help society at large.
Making victimless crimes legal wouldn't help with keeping innocent folks out of jail. Everyone in jail before trial is innocent. It doesn't matter what they are charged with - before trial, they are innocent. Even if the crime committed had a victim.
