Like bills do require a full office in 2021.
I pay all my bills by pressing a button on my smartphone. And that's because I like to review them, I could pay them automatically if I really want to.
Do you not have any personal arrangements more complex than 'pressing a button'? Investments? Correspondence with people? Reviewing agreements and portfolios? Do not you do things like budget? What about hobbies that require desk-work and making calls? Volunteering and work with charities? What room do you do these things in?
