I also find perspectives like yours very perplexing. Debt is not charity. It is not charitable to provide debt to someone who cannot afford it. Not for the debtor, nor the lender. I've seen people suffer for years drowning in debt they could not afford. I've seen people with mortgages (variable rates in foreign currency) that went underwater when the rates and currency exchange shifted the wrong way. Bankruptcy is an incredibly painful process to go through as well. Debt is not charity.
Banks also do not just give out big loans (no matter what your credit score is) unless there is collateral. It is clear as day, that the bank valued the collateral to be low or inconsequential (i.e. judged one property at land-value at $1/sqft and $0 for the building). So there was no collateral for those loans, because redevelopment of those properties was expensive, with lots of risk. Why do you think it hasn't happened yet? Why do you think these properties were standing there rotting away? Why didn't anybody take a flyer on those, given how inexpensive these properties probably are? Because there are major risks associated with redevelopment. In our city, a property, seemingly in a prime location, stood abandoned for years .. turns out, the property was cheap, the land was cheap, the environmental cleanup necessary for redevelopment, was not.

Says who!? Have you actually tried? Our company was only extended a line of credit years after we were in business, and it was collateralized against purchase orders and revenue (and we had to provide lots of documentation to prove those). Banks do not want to give out loans with even a little bit of risk associated. They are not like venture capital firms and haven't been for a long time.
