Scooter. A nice one will cost you about Rp20 million to buy.
License to ride a scooter - Off to the main cop shop in your area.
Working - Difficult
Working remotely - Hardly likely to be a problem as long as you tell everyone your cash comes from pensions, investment, or whatever.
Internet - Easy if it's just emails and browsing. Not always easy for streaming depending on where you live.
Renting a place - Easy, but shop around so you don't get ripped off.
