I work remotely and your advice is good sound. I make sure I separate my living space from work space. I'm fortunate to have a dedicated office in my house, where I only go to work. I've also used local hot desk spaces.
I think it generally works if your working in a remote first organisation. When an org has a bit of remote and mostly collocated the organisation need to make sure any comms include the remote team members.
I've not encountered loneliness as I have family and friends who live with or near me.
