I can't speak for Germany or the Nordics, but here in the Netherlands the government is doing just about anything in their power to keep foreign competition from our rail network. The only lines serviced by foreign operators are the ones that would cost the national operator more than they would bring in and (some of) the international train services.
Our "high speed" rail is a joke. The trains themselves are fine, but the bridges over them are too brittle for the train to actually achieve high speeds, so it's operating at less than half the speed Spanish high speed rail is operating at. If anything, the success of the Spanish rail operators is an argument in favour of actually bringing competition to Dutch rail operators.
That said, the Dutch railway network is very different from the Spanish railway network. We're a small, densely populated country with many stops along just about any track, barely giving most trains time to accelerate even between larger city centers. The network is complex, the rails are extremely busy all hours of the day, our trains run on an idiotically low voltage and two trains with a dozen minutes in delays can back up the national train grid in no time if they slow down in the wrong spot. There are only a few long-distance high-speed rail options that make sense, some of which already sort of exist (Eurostar to the south), some of which our neighbours plainly don't want (any Dutch rail project crossing into the German border), and some of which are hardly financially viable (trains from the big cities to remote parts of the country) in a country that doesn't want to spend money on public transport.
