may I suppose you use a web browser?
You may.
if yes, is this complexity needed or not?
No it is not, because the browser is not "needed".
Neither is OS X or the MacBook upon which they run.
AFAIK the only things we _need_ are:
air, food, water, shelter and reproduction (have I missed any?):
all the rest is choice.
Just because someone choses to use some piece of unnecessarily
complex technology
does not make it a "need", it makes it a "want".
We don't need web browsers, video players etc.:
we just like having them.
If you then say "I need it to do my job",
then I say that the job is your choice (as is mine using linux etc.),
and so ad infinitum.
If the government mandates use of a web browser,
well, we voted for them, right?
If you don't fight tooth and nail against them then it's your choice.
In other words, I use the shit, reluctantly,
I don't increase the size of the pile.
While I'm not happy with the situation,
as least I'm not exacerbating it.
Plan9 with a usable web browser would be a fine idea.
Unfortunately, the pain and complexity that goes
with making that fine idea into a reality would drive people away
from plan9.
