Guest checkout is a preferred checkout option for plenty of customers who don't want to go through a long registration process. It is also an option that allows them to place orders quickly. 

However, some merchants falsely assume guest checkout deprives them of a marketing potential since they can't gather valuable info about their customers.

Not with the Magento 2 Guest to Customer which is very easy to configure and beneficial at the same time.
