Withdrawals: Will staked coins increase or decrease?

The obvious outcome is that the size of the staked pool will shrink because people can exit. The things I'm not sure most people get however are:

1) Withdrawals, just like deposits now, will be rate-limited. Even if 20% want to exit on day 1 that won't be possible, they have to queue.

2) The number of people willing to stake when withdrawals are "X years away" seems much lower than the number of people willing to when it's possible. If the pool of potential stakers post-withdrawl is 3x higher, it could easily cancel out those who exit.

I myself won't stake until withdraws are live, and I plan to stake once that's possible. Do you think people like me outnumber the people who are currently locked in that will exit immediately?
