Absolutely. If they end up making access to the deep and dark web impossible through commercial Internet infrastructure, the next logical step is cracking down on alternative Internet infrastructure. Overlay networks like I2P, Tor or Hyphanet can be a temporary safe haven, but ultimately a government can make it extremely hard for uncontrolled platforms to stay up. I guess we'll have to fight for it if push comes to shove, and it's looking very bleak.
