Dollar doesn't really collapse. Just for study, research how they do bail-ins now and do like a Greek style depositor bail-in... all they do is limit daily withdrawals. If you can only withdraw $1k per day or something, unless with special permission, banking system never collapses. The FED and other entities got their fingers in so many places they can basically stall crashes indefinately, flushing out the crashes into the underbelly of markets in various places. Meanwhile life goes on and a collapse doesn't happen. Just notice how the price of a dollar might lose 50% of it's value in 5-10 years. Measured and steady is how it crashes these days.
