They stop short of quantifying how much is "easily". They know that the virus is still activated on surfaces for a while depending on the surface but no one has determined if those populations are large enough or stable enough to infect. So we are stuck sanitizing until this gets resolved, but I don't worry so much now when I make a surface touch but forget to clean my hands for a while. I still treat every incident where this happens as a possible contamination though.
I would think there are people who have not had any contact with others but touched an infected surface and didn't wash properly afterwards (such as me since I don't even shop in stores) so if no one at this point can trace such an instance to Covid infection then it must be very hard to get from contact, but that is just my guess - only time will determine if no one ever shows up positive from contact transmission.
