It's funny, but more realistically, a hoarder at this mangetude usually has strong emotions tied to items. It can be that it reminds them of something or someone, or they feel a huge amount of guilt at even the thought of tossing it. Could be guilt of climate change or guilt of the item's purpose being wasted. It could be as simple of being afraid of being in a situation and needing one again.
Even the hoarders that explain their horde by way of earning money (this will be worth something) is just using it as an excuse to horde. They tend to like the idea of what it could be and enjoy imagining the project, but don't actually enjoy the action of doing the project. The connection to hoarding items is hoarding the imagination of it, and having the physical thing makes that imagining much more real to them.
Still, it's a funny comic.
