Unless someone finds a way to advertise nodes that doesn’t depend on the entry point then yes. Consider this example: https://github.com/bitcoin/bitcoin/blob/1b2460bd5824170ab85757e35f81197199cce9d6/src/chainparams.cpp#L112 if someone takes down those domains it is game over for a new node until someone updates the code.
Really? I just bought Strongbox Pro for 99€…
