More seriously, companies like Spacious are doing what you're describing. Much cheaper than WeWork. You work out of an off-hours restaurant, but it's a designated quiet/work zone and they have free coffee. I'm not affiliated, and I actually didn't enjoy it, but it might interest you.
I could sit in relative peace and solitude while I get my work done.
