This is another useless use case for any coin or project, if you build any project on this it will never be popular, many projects did already and they are no where to be find today, just because blockchain is the biggest thing today doesn't mean it's needy in every business areas
Well, creating a new coin or token for something like that is useless and they are doing it just to scam people and grab their money. but this is not true that blockchain technology can't help in any business area. I think somehow blockchain technology can help in any aspect of life and business if it's implemented in right way.
but sadly these people have no intention like that.
