Current "fast growth" lumber is already operating on a ~10-20 year time frame. Getting to something old growth like will probably need like over 60 years at a minimal. Reclaimed wood (depends on your application) is currently only like <5 times as expensive as new growth product. While it's definitely true that the supply of reclaimed wood will dwindle, meaning that if you start such a project today, you'll probably be able to command a significantly higher price multiplier in 2090... I think that sentence alone explains why this doesn't happen at any significant scale.
