Your DeFi criticism had a point until you made the artists stand trial for the price chart.
Yoeshi showed you a physical painting connected to an interactive work, answering your exact question. You dismissed it on sight, told the artists to try experiencing art sometime, then called the people here losers.
Ten years in Tezos should give you enough perspective to aim your anger at the people making the funding and strategy decisions. Artists didn’t drain the liquidity. They found something the chain was good for and kept using it while much of the rest stalled.
Tezos has plenty to answer for. Send that invoice to TF. The artists already paid their own tab.
