The problem is that databases solve a real world problem: businesses and people need to store data, and the database is literally the solution for that.
Cryptocurrencies have so far not resulted in a compelling use case. All that we are seeing is a questionable solution looking to solve some as yet undiscovered problem.
The parent comment is a bit flippant, but I agree with the thought. The entire crypto industry is rapidly becoming a bizarre and convoluted rube goldberg machine that is completely impenetrable to anyone but the most ardent zealots. Even more, as an outsider it seems like everyone is in this echo chamber of back patting and "with just this one more buzzword bingo sounding feature, we'll have unlocked the true potential of crypto".
