Sorry Kevin, but like so many posters you are basing your argument on the facts in the context of today. As in my previous posts, we must think about 25, 50 or 100 years time and the conditions relevant then. Life will be very different.
That's my point exactly. Travel is becoming less important in order to be able to do business, and it may be completely irrelevant in 100 years time.
IT, working at home, is all very well now. But in years to come, if not now, we must return to manufacturing, in the physical form, and that will require workers to be on a site actually building things. We need those industries in the Midlands and the North generally, so we need a large commuting / living population in those areas to revitalise the commerce there, and for Great Britain generally. We need to move people at high speed around the land and from Europe to get the best for our industries for their expansion.
If we are to promote manufacturing then the government would be better off halting the erection of the artificial barriers to manufacturing that have all but driven it out of the UK in recent years. The green agenda and employment conditions in the UK has driven it to sweat shops in the east where child labour and CO2 emissions are of no concern. If we are to have decent standards of living and constantly reducing environmental impact then manufacturing doesn't belong here. On the other hand, perhaps we should be imposing tariffs on imports from places who don't meet our standards on these aspects of manufacturing?
Either way, marginally faster trains won't have any impact.
As I said before, Victorian England was given a massive secondary boost to it's Industrial Revolution by the railways moving around the workforce to were they were needed, away from the land. In a country with by 50/100 years time perhaps 75/80 million (?) people we will need rapid transport that is sustainable. Sorry, and I hate saying this myself, but the car is going to become a liability for anything but local travel. The road system will never cope no matter how often it is extended, and it will be far slower travelling on them than today!
The industrial revolution has moved on from this country to elsewhere, though and it won't come back! We need to look to the next revolution, whatever that may be.
As for eliminating the car - I agree. It won't scale up the the requirements of a growing population, but the barrier to other forms of transport is the last mile. We have been making the mistake for decades of not integrating other forms of transport such as rail into housing developments and now have large swathes of conurbation which is only accessible by road. Once you've had to get into a car, you might as well make the whole journey by road.
So, the job for rail is to reach a larger percentage of the population easily. Not as sexy as trains doing 200 MPH, though, so that'll get no political support.

I would add though, in addition to a HS1/HS2 passenger lines, we must have a superfast, super gauged, freight lines (HS3?) to take freight off the roads, which I predict of course will become unviabal for fast movement.
Yes, it would be good to get freight off the roads. It doesn't have to be high speed either, IMHO. It'd be significantly faster than HGV speeds to use conventional rail. Again, it's the last mile, though. I have no idea how far I'd have to take a container to get it on the rail network, but, I suspect that, once I'd loaded it onto an HGV, that would be far enough that I just wouldn't bother with the rail option unless it turned out to be stupidly cheap.
So, in conclusion everyone has got to think "tomorrow" not "today". That is what the Government are trying to achieve and full marks to them in a field of otherwise growing failure!

I disagree. They are instead looking at networks built in mainland Europe decades ago, to solve the transport problems of mainland Europe, thinking "why haven't we got one of those? I'd like to see my name on that!" and trying to play "catch-up".
