I don't think especially with youtube anyone needs a personal trainer...Now if you are an athlete or want to become a pro bodybuilder/power lifter etc I could see using a coach but just a regular cat who wants to become healthier just look at the content on youtube. Most trainers don't know how to get a person In shape and also don't let someone be your trainer just because they look good...They may have won the genetic lottery, be on juice, potentially know what they are doing...But more so their whole hustle is for you to not actually get into shape because if you do get in shape what do you need them for? Most trainers I've seen can't legit program a 4-8 week workout plan that makes sense or a nutritional plan.
