In countries, such as GB, where PTT is still strong, maybe,
it is.

But, we are talking about the future.

It won't, or, at least, it is safe to assume it won't.

Note also that I assumed people will use ISPs not only
as home users but also as mobile and corporagte users.

Just 4 or 5 times more than the current number of routes?

It, surely, is too optimistic.

Moreover, even it costs a lot, not only for memory and bandwidth
but also for operational costs such as BGP convergence time,
possibility of route flapping, possibility of bogus route
and so on. 100K is already too much.
