Coinbase or Bitpay are optional facilitators, for people who want to buy or accept bitcins
Yes, they're optional for merchants, but for average consumers who want to buy the same goods and services they can buy with fiat, it becomes an unavoidable potential point of failure. If these services go down, the consumer cannot spend their coins, they rely on 3rd parties to turn bitcoins into something that businesses actually want to accept in exchange for their products.
