It's just another option for people. I like permanent tattoos as well, and I love checking out a person's tattoo's (though I'm not fond of 'full sleeves' and similar, where it's hard to pick out the individual tatts).
The 'story' point reminded me of my response to people who say "Yeah, but what will your tatts look like when you're 80? They'll look terrible": "What, you mean at the end of my time, after I've enjoyed them all my life?"

Which is a good point. Current tattoos are also limited in life span. Even before a person dies, the tattoo will start to blur. So really these guys are just lowering the life span of a tattoo to something within a persons life. Which is already a thing since you can get tattoos removed by laser.
So all they have done, should they succeed is make things more convenient.
