This argument is disingenuous. By the same token, focusing on PvE is a good idea, as proven by WoW. And focusing on PvP is a good idea, since games like DOTA(2), LoL and WoT have all been really successful.
The real question is whether, in AoC's current state, resources are better spent on player housing than on PvP updates or PvE content.
In terms of resources needed to implement it, the most authoritative information we have is the reply by FC to the Your Voice questions, which Azmith quoted above. In itself, this clearly rules out that player housing would make sense for AoC in its current stage.
The other question is the benefits resulting from this use of resources. I can't be bothered to look for the old summer questionnaires - but from what I remember it was clear that crafting was not a main priority for AoC's playerbase. Sure player housing, if done right, might attract some new crafters - but to recruit a significant number of new players, FC would have to invest in marketing AoC, which they clearly are not able or willing to do at this stage.
So without the shadow of a doubt, FC's limited resources are better spent on issues other than player housing.
For the sake of completeness, here is the link to the Your Voice answers:
