At a high demand time, it could take hours to complete a transaction (if it even went through at all) and with an outrageous fee up to dozens of dollars.

Bitcoin has never been known for time efficient nor competitive fees (except for maybe in the beginning when nobody uses it).

At least you admit people use it. Bitcoin lightning enables transactions in under a second for pennies in fees, it’s been around for 5+ years. Your information is outdated. In the last two months, Nostr users alone (decentralized twitter clone like Mastodon) sent each other 2.6 million tips (individual transactions) over Bitcoin lightning. None of that requires an on-chain transaction, none of it required high fees. It works. It scales. It continues to improve.
