A .com, or .whatever, is has always been and will always be infinitely more personalized than any myspace or the like will ever be. Those are just for getting news out, as were a personal site can really show your own thoughts, ideas etc. etc.
This is just my opinion though, but it would seem at least a few agree with me...
almost all bands seem to disagree with you these days...

honestly, i don't know what's worse: a totally outdated official band site, or none at all (that seems to be the main argument for taking a band site down, and i think it's a pretty good one).
But i still agree that an official website needs to be there. Most people would still go to the myspace page for hot news, and that is why the site should be designed in such a way that it doesn't look outdated for a long time, i.e. it doesn't have to be updated more often than when a new release comes out (so, like once a year or even less often). That should be doable, right? If there's no News section on the site at all (just a link to the official Myspace page with latest news), it won't look outdated.
I think an official website should be more like an archive, an anthology of a band, which contains all kinds of historical stuff, like video footage, photos, interviews through the years, maybe some rare stuff like songs that were discarded/never recorded etc etc. And it would also be handy if there was an official merch section where you could order from (like Opeth site, f.ex.) But this is more of a "nice to have", than a "must"...
But the rest is not so impossible, is it? I mean, it doesn't have to cost that much, you can get pretty cheap hostings these days, and digital artists from the Easten Europe work almost for free and create professional top notch eyecandy...

not to mention the whole lots of us who are dying to prove useful for you guys and willing to do this stuff for free
