A couple of browsers can connect to Tor without installing anything extra so maybe as the internet is tightened down more browsers will add this ability. To your point though it is still slower and people despise latency so the faster sites will likely win out.

In terms of legality it is not clear to me that countries will enforce the laws of other countries even if they are allies. Global trade is changing and I suspect that could affect international enforcement as dependencies shift, maybe. Time will tell.
