Is Detroit too far gone to be worth the Man power,Money,and investment such as entirely new infrastructure?

They make special suits and respirators to eliminate asbestos while protecting workers.
I used to remove it from old heating and cooling ducts without protection. It's not like you're dealing with Chernobyl-level toxicity. I didn't do much asbestos removal, but it's not as horrible and deadly as one thinks. That's mostly trumped up so people can get gibs for having worked around it for years and years. Tons of products used to be made from asbestos. It's not healthy or good, but it's also not as unsafe as they make it seem. The issue with asbestos is the tiny particulate that dissipates when you disturb it.
Wear protective gear and you'll be fine.

Airlift the city and drop it in the middle of the australian desert

Yeah, they jacked up the rest of Wayne County's water bills to make up for their shortfall, too.
My water bill went from ≈$30/month to ≈$45-ish per month.
And that was after it being consistently the same amount (plus or minus a few bucks each quarter) for the few years I lived here before all that nonsense went down.

How would you convince them to stay and rebuild the city and pay off the debt the niggers accrued?

Please god no

But they never will.
Detroit has an oppressive tax policy. Even if they give breaks to businesses for locating in the city, there's still two other strikes against them:
1. Employee city payroll tax - Everybody who works in the city pays tax to Detroit (2.5% for residents; 1.5% for non-residents, IIRC)
2. Every business operating in the city has to have a certain percentage of city residents working at their business, or they get penalized.

Was there any name the strikes went by? I'd like to read about it

If I lived in America I'd buy up a lot of Detroit property, shit goes for penny and one day in the far future will likely be worth something.
