The decision to share a seed phrase with someone is entirely personal to that person if their family has reliable descendants to provide them with that seed phrase. There are many elderly people in the world who have no one to care for them in their final days, even if they have a lot of money. In fact, this happens as a result of social values and family breakdown. If it is the case that a person has a large number of bitcoins in his portfolio but does not get a chance to pass them on due to the lack of a proper successor, then you can call him a loss rather than a waste, even though if he had a family of his own he could have served them.
If that person intentionally doesn't share his seed phrase with anyone, you can call him a waste. If he was a great person, he could have donated the bitcoins he had accumulated in return for a lot of hard work to an orphanage or some other service organization.
If any bitcoin investor is dying and has no successor to pass his bitcoin to, taking this advice is not the best thing to do. Bitcoin is one of the best assets in the asset class. It would be a waste of time and resources if a dying investor donated his bitcoin to an orphanage or some other service organization because they would sell the bitcoin cheaply immediately they had access to it and use the money to run the affairs of the orphanage or the other service organization. It would be better if the dying investor passed his bitcoin to institutions that teach and hold bitcoin for long-term purposes or to a forum like the BitcoinTalk forum, because they know how good it is to hold bitcoin, and they also have a strong means of generating money to run their affairs, and they don't wait for people to donate money for them before they can run their affairs. Since most forum members know the freedom and profit that come with holding bitcoin, they will not sell the bitcoin in a hurry. They will hold the bitcoin as long as it is still existing to see what will really become of bitcoin. They can even decide to hold the bitcoin in remembrance of the dying investor and even set out a day to celebrate his hard work and smartness to accumulate bitcoin, and also donate the bitcoin in a place where it will be safe.
I completely agreed with you on this @ mayor of ogba. However, that's reminds me of an African proverb that says,
Ọjị n'anọte aka na ọnụ ndi maara uru ọ bara, meaning Kolanut last long in the mouth of those who knows the value. [Wealth stays with those who knows first the value.] the Bitcoin deserves to be cherished and giving to those who actually know it's value and the true potentials it holds. Even in a real life people tend to miss use what they don't really know it worth and value, given the Bitcoin to the orphanage will never be a better choice, just as you have said, they will never hold it, neither will they even sell only part of it but all will definitely be sold even at cheap, simply because they are not optimally informed about the true potentials that Bitcoin holds.
