Materialise row-number column

On Microsoft SQL Server 2012, I would like to materialise the result of the row_number function, because I hope it makes queries running faster. I considered to make a view index, or to add a persisted computed column to the relevant table. I fail with both. How can I achieve what I want?

As example, let us look at an address table with multiple addresses per person.

View index

create view nrview with schemabinding as
select
  row_number() over (
    partition by person_id
    order by valid_from) nr,
  address_id,
  person_id,
  valid_from
from address

create unique clustered index ix
on nrview (
  address_id,
  nr,
  valid_from,
  person_id)

This fails with error message 10143:

Cannot create index on view "mydatabase.dbo.nrview" because it contains a ranking or aggregate window function. Remove the function from the view definition or, alternatively, do not index the view.

Computed column

alter table address
add nr as
  row_number() over (
    partition by person_id
    order by valid_from) 
  persisted

This fails with the error message 4108:

Windowed functions can only appear in the SELECT or ORDER BY clauses.
