The physical constraints of proof of work is what makes Bitcoin ultra-superior to any purely software based consensus mechanism.

Proof of work allows for only a single winner takes all protocol. This is what you want. This is what's best for humanity. It's also consistently the most profitable long term.

All other monetary systems have expiration dates due to human greed and corruption.

TLDR: Bitcoin is incorruptible. And it's the only money that is.
