I think you're hung up on fractions, while the business logic is obviously hung up on the value. The cost of wood has gone up, but wood is a critical element in construction. What is the "value" of paying $100,000's in lawyer fees?

It's like buying a home and having to pay 10% in agent fees and having a 6 month arbitrary holding period while you are still having to pay the mortgage. "Well the money you're losing is less than the cost of the land!" you would say. lol.

That's basically what's happening to construction projects, it's an industry-wide show-stopper regardless of what fraction it is of the land price.

All the links I've shared confirm that these costs are the prime-driver of project cancellations and projects dying on the drawing board, not that the costs are larger than all other costs in an absolute sense because obviously mortgage payments while you're waiting for lawsuits are less than the whole land value itself.
