A consequence of your first two points:
  1. Tabs belong in one place in a document; and that place only. That place is in between the left-margin and the first word character. This is the tab-zone.
  2. Nothing other than tabs, belong in this tab-zone
is that you can't do any vertically-aligned code. For example, if you want to split a long while- or if-condition onto multiple lines, you can't align things for readability in such a way which is tab-width agnostic.

So, I would disagree with your point 3. Not every line of code has an explicit indentation level, in particular continuation lines do not.

I prefer space indentation for these reasons.

A counter argument could be made that such long lines are always bad, or that one should use a sufficiently wide line and so that line-splitting is never necessary. But you'd need to establish that point before having a tab-v-space argument, since the 'pro tab' position depends on it, I think.
