A question to consider: when you go to a coffee shop alone to write, what do you do when you have to use the restroom? Do you pack up you laptop and such and take them with you or leave them there on the table/counter with your half drunk (completely finished) cup of coffee?
It would be harder for me to replace my notebook with ideas, first drafts, and ramblings, yet it’s more likely that someone would take the laptop. But what is the likelihood that that would really happen? Do you risk it?
