I think it's very important that we still have brick and mortar stores. Especially the smaller and more independent ones. It's not a good world to live in when our goods distribution is handled by one or two insanely large megacorps. And online access can be revoked at the whim of the parent company. It's super convenient when Amazon has anything I want to buy (or a knock off :/ ) and I can click a button and in a few days it arrives, but it really feels bad to using that. I know amazon employees are treated like dirt. I know it's terrible for the environment for me to having items individually shipped to my house. And I don't get to go out and laugh or joke with the employees of the shops. And it does nothing for the economy of the place I live.
I really don't think Bookstores are a waste of space.
