The cash flow would be fine but I think he'd experience a level of withdrawl symptoms facing a reality of relative silence. Sure he could still use his phone to tweet and scratch the gacha itch but imagine someone who uses their jahb and the alms received to facilitate their ongoing denial of reality - to distract themselves from the fact they have no friends, no genuine interests in anything beyond wasting their time and money on hollow jpeg wins and comfort food.
I have a wife and son he might say. They spend so little time together that it can (probably) remain cordial between them. Personally though I feel like you don't really get to know someone until you've done things with a partner like going on a vacation together or been in some situation for an extended period where there's no breathing room. This is when you get to know what they're really like and I'm not sure they've been through this since she moved in. Sure they took a trip to CT and got married.. then came back talking about how they basically both hated the experience and the only positive draw for phil was recalling all the food he shovelled into his pie hole.
Faced with a break in his autistic schedule (which gives him the shakes for fear of being abandoned) and left to deal with the deafening silence of his empty materialistic life I think he'd start to snap for want of some way to occupy himself when he's not able to watch an up to the minute tip counter. He physically comes unglued at the hint of anything in his world not operating as it should, hops onto his PC in hope it'll have all the answers while he rocks uncontrollably. Reality outside the pigpen seems like a living nightmare to him when someone isn't on call to tell him what to do with himself. It's an interesting and fairly miserable look into someone completely dependant on the internet in every facet of their life.
