Ideally, yes... although it's a fine line between that and helicopter parents. Practically speaking it's not always feasible logistically with working parents and such. 99.9 percent of coaches are great people. Like 99.9 percent of teachers, 68.354 percent of priests, etc. You can take reasonable precautions but a parent cannot reasonably protect their child from every potential opportunity for something bad to happen. Honestly I'd be more worried as a coach in that situation than I would be as a parent. I don't even meet with female employees at work 1v1.
