This is not exactly true, V has a Delamain that considers itself her property. She can also most likely sleep on Vics couch for a couple of nights. And regarding money, I'm pretty sure that if she calls Reed and accepts the Langley gig they will arrange for her to survive the night. Other than that Kerry has already confirmed he can give V some money.It is a fitting end but a sad one. Silverhand is totally gone (in contrast other endings where he at least merges with Alt or take V's body), all of V's friends have left or changed in drastical ways. V has no money, no housing, no food or drink (no inventory). V is a sick chap now, can barely stand, can walk slow only. He's now worse off as any average NPC. He disappears in the crowd but where will he go? Where will he sleep? How to get his next meal? Most likely he won't survive the night.

Surviving isn't the problem, living is.
