Giving web pages exactly the same power as native applications is not, and
should not be, the goal. The goal is to enable many of the the same
use-cases. Native apps can do anything they want and installing them is very
risky. It is one of the benefits of the web that web pages you navigate to
do *not* have that sort of power.
Installing native apps from untrusted sources is scary. Visiting web pages
should never be scary, especially since the average user stumbles upon many
more web pages in a given day than native apps they would install. The
desktop has no equivalent to the lightweight step of visiting a web page.
Giving "installed" web pages (e.g. extensions) more power is much safer than
silently giving all web pages that power.

I don't yet see any evidence that this is true. Certainly, enabling
botnet-like power would enable a wider class of powerful applications.
However, the corollary may not be true. It may be possible that we can add
all the power we need to the web without enabling botnets if we are use-case
driven and think of more constrained APIs that meet the same needs.
