You can think of bondsmen as essentially very specialized financial institutions. They provide loans to people. If you have a $5000 bond, you can pay a bondsman $500 to front the other $4500 for you. If you make it to court, they get their $4500 back and it's all good. If you don't make it to court, they are incentivized to find you to make sure you make it to court. They are usually not pleased to do this.
You are not required to use a bail bondsman to post bail.
There is no $250M loan. Should he fail to appear, he and each of his sureties (his parents) can be pursued by the court for whatever remains of the balance of the $250M bail amount.
There is no actual $250M that changes hands until then (or, realistically, after.)

When push comes to shove, morals aren't easy to come by. Especially not when put up against some downtime with the family.
If you use a bondsman, you lose the 10% no matter what. If you use a bondsman and skip town, you're out 10%, and they're out the other 90%. Hence why bondsmen employ bounty hunters.
There’s no way his parents are forking over their home to a bails bondsmen. There’s also no bail bond man who has $250m.
In most states, 10% is closer the legal maximum than the minimum premium for a bail bond (it is often exactly the the legal maximum, but in NY the maximum for large bail amounts is much lower, asymptotically approaching 6%.)
