Hmmm. interesting, but I totally disagree with you, I know of a number of people who have a certificate with a special star named after the loved one that has departed this world.
They get great comfort and joy when they venture out on a clear night, look up at their special Star, and give great thought about there lost loved one.
These people I know had this done for them for free, there was no money exchange, but done out of love for them, and there family.
A few years ago our dear friend and neighbour lost her husband to a brain tumor, he was 34 and left a 6 week old daughter behind and a loving wife of equal age.
I did this for them because, I could, and they hang it with pride in their home, and reflect on it often, and often point to that Star when outside.
There is accompying certificate that gives a full description, of the selected Star, plus where it is, name coordinates etc, so it can be located wherever they are.
I have done others as well, for free, and see no harm in it what so ever
