So should a phone number be required or not when ordering something? It's commonly used to text delivery times etc. Or what about a contact form where you're given the option of a call back. Or what about if it's a government form and they're legally required to ask race, gender etc, but you aren't required to answer. I don't disagree with the sentiment, but you very quickly run in to situations where you need optionality. It's like making apps easy to use by having no options. Great in theory but annoying in practice.
