1. Considering I have a pile of loot I've amassed and that I am just waiting for Creeper's inventory (specifically, his 5000 gold) to respawn, no, making gold is still as easy as ever.
2. I didn't know my various safehouses (home in Vivec, Indarys Manor, etc.) were reachable by immediate boat/silstrider travel. I still had to run (at an extremely slow pace) to those places or waste my one mark on one of several safehouses. The Ald'ruhn Fighter's Guild (one safehouse) may be near a siltstrider/teleporter, but my other safehouses, especially those not in cities, are a different matter, and I still have to run from a teleporter in one place (after teleporting) to the siltstrider in another, and then from the siltstrider to a boat, as well as back. Also, if I found two interesting dungeons at once, my character will not be able to loot both and carry the loot without overencumbrance, so I either need to take away my one mark from one of my safehouses, which I just cannot do, or I could use that mark to allow me to go back to the dungeons, but then getting to my safehouse is a pain. There's too much running around, on the same paths included (to my home, to that other fast-travel service, to that dungeon I saw earlier but couldn't loot, back to that Daedric shrine, etc.) that I (I, me, singular) just did not care for.
3. I (again, I, me, singular) do not consider it immersive. I consider it a nuisance, I consider it to be tedious, and I consider it a reason why I just end up getting bored and turning off the game.
