No, she did it so she could hide how much money she has, to avoid taxes. Not to 'avoid the hassle of travelling'. You don't fucking hire a law firm and pay large amounts of money so they can hire someone to pretend to be the beneficiary just so you 'avoid the paperwork and stuff'.
When you invest in a bank you are doing them a favor, she doesn't have to be there in person to close her account she can have someone else do it for her, but in order to bring the money back she has to report where it came from and everything and eat the 66% tax I think it is in the US when she brings it back, so she probably ended up losing out everything she made using an offshore account and the US government gave her the same rate she would have gotten if she just did the same thing in a bank in New York essentially in the end.
Maybe she did try to game the system, I guess we will never know unless they reveal all the info, but it seems pretty easy for BBC to hold alot of information back to hype up the story. I looked up her name and there's no mention of fraud or any other court cases
Also alot of money is being transferred and moving internationally, it requires alot of work. Hiring a firm and paying $30,000 sounds about right, they are charging $1000+ dollars an hour plus paperwork and other legal fees. Most legit people doing this are leaving the money in the offshore accounts and never bring it back because it's not worth it to bring it back, you will get taxed the same rates as if you never invested it overseas, unless you live in some sketchy country and know the right people. You can live like a king in South America collecting tax free interest if your account is large enough it will pay for itself for the rest of your life, and Panama grants automatic residency to investors. If enough media attention shakes things up you could also see this tax haven utopia disappear overnight if enough investors pull out and alot of people will lose their money. So I guess there was always a risk to start with, but people should be able to do with they want their own money right?
