And there is a third group... people who want to collect something... like stamps, coins... and todays generation has discovered NFTs. If you check opensea.io (largest marketplace for NFTs) you will find out, that most people are buying and collecting these items.
And this third group is by far the largest

I have not seen a single person who isn't buying a token for profit making. The people you mention are also "investing" in these tokens thinking they would appreciate in time. Something like the dotcom bubble but without the bubble.
Yes, the same you can do with BTC... right clicking it, you can create Bitcoin... who would buy it?
No, you can't create bitcoin out of thin air but you can create an unlimited amount of the same token out of thin air with virtually no cost.
