In a vacuum, that is a fact; however, for most of the things people get warrants out on them for, they know what they did. If they don't know it was wrong/a crime, I would say that's more on them than on the system.
You can get warrants for unpaid moving violations. For stuff like that, I think notification by mail would be more efficient. Like "you haven't paid this so now there is a warrant out for your arrest," just to inform the person. Yes, going against the reason for not notifying, they may still commit several more moving violations (like speeding) before being caught, but tons of people do this, sometimes right in front of cops, and a lot of cops look the other way. Now if someone has done something violent, left a victim, no, you wouldn't want to notify them because of the chance that they'd either go do more harm to the victim (and now the police/the system is liable) or they will do more crime that will result in more victims, and again, liability.
"Too expensive" means "beyond what the market will bear. Objectively, the Switch 2 didn't cost enough — there was some other higher price that would have given Nintendo numbers such that while it might not have sold quite as well, what it would have sold would have made up for it. Would the market bear a $500 Switch 2? Maybe. $600? That, I doubt. $450 was a bit high for my liking, but the market bore it just fine and now it's thriving.
