Most transactions don’t need a decentralized trust-less value transfer. But bitcoin is not only attempting to displace the small sliver of transactions that DO need trustless/decentralized
Making that trustless means I am open to scam sellers, and have to trust the seller (who stands to gain if they can trick me) instead of now where i trust the bank and the conveyancers instead.
Cryptocurrencies support escrow transactions, where a mutually-trusted third party (e.g. an arbitrator) can decide whether the transaction should go forward if buyer and seller disagree. This is still "trustless" compared to other systems because it only depends on mutual trust wrt. each individual transaction, not on a pre-defined central authority.
I’m not saying blockchain is useless - just i see no use for it when it comes to the way that 99% of americans buy their house - and if 99% of americans switch to btc for this kind of transaction the carbon cost would be massive.
Proof of Work Blockchains use the same energy whether there are any transactions or not. The idea that your participation or lack thereof deters demand in protest of the carbon footprint is just … wrong. Inaccurate.
its mind boggling… I would say more but I’m reserving my thoughts in case you have a rationale that is more convincing
