If you know what to do more than just whine about how it is going crazy, then you might be able to profit from the frenzy that is happening, yes people are saying that NFT is a bubble but we don't know when it is going to pop and with that knowledge we can be able to make money while it is still growing and not yet popping up.
So, this has nothing to do with the gap between poor and rich, it has nothing to do with decentralization, being your own bank, freedom, you explained it quite clearly although you probably did this unwillingly.
Make money before the bubble pops!
In one single line, you managed to align NFT with ponzi schemes and brought to the surface what everyone knew about those, practical use zero, 100% way of making a quick buck out of nothing.
The NFT craze is simply unsustainable. Altcoin valuations are through the roof. And even the most fundamental (and sane) asset in the cryptosphere, BTC, is arguably entering frothy territory.
There will be a time when this speculative bubble comes crashing down, although it is not entirely certain when that will be. It could well be years given the current sentiment.
I doubt it will take years for it to come down, in the past collectibles like these have made it through a long period because there was a manufacturing process, there were limited things to produce, communication channels were not that effective, right now it's a different game.
Every single useless thing can become a NFT, transactions are instant, collectors can follow trends in minutes, this of the tulip many but in a digital form where bulbs take seconds to create. It will a ot faster than the beanie babies craze.
