And not all renting out is rent seeking! On occasion in cities with decreasing home prices, the landlord is subsidising the tenant. That is rare though!
I am on holiday now and want something similar. Get me from A to B but with a memorable heuristic that I can use if I leave at any time. E.g. "if you catch a 134 or 175 bus to Kings station then get the metro 3 stops to Cental station.". Even better if you add some landmarks.
This may exclude some clever routes that shave off 3 minutes if you do the correct parkour... but it means I can now put my phone down and enjoy the journey without tracking it like a hawk.
Turning that on its head, maybe you want something like a 90s shareware lost, curated by someone. Then the games you'd play for free are now ad free (the game is its own ad to get more levels). And you get that curated list. But yeah less money than dialing up ads to 11 while trying to find the whale who'll spend 1000 a week.
