It won't be safe at all unless they get everyone else's permission to deorbit every single low earth orbit satellite and spacecraft first. That's the main reason why I think the space elevator will never happen, you'll never get every other nation to agree to it. They would essentially be dependent on you for any access to space (although higher orbits would still be viable, the risk of not making it to a high enough safe orbit would be too great), access you could hypothetically revoke at any time, and at the same time your elevator would be a giant target for any rogue states.
