You could try being a bit less aggressive in your postings. I've just looked at that 2002 thread you link to, and I note that some people had the same "I've done it so can't see why everybody else can't" attitude as they have today. I also note that there is the same bu11sh1t in there as we hear today e.g.
For starters, the TMA's are already full, as are the airways feeding them - hence slot times and height capping
which is nonsense. You can do a flight at FL100-FL200 right across any bit of Europe and you are very unlikely to get visual with anything, short of FL350 traffic high above. I've already explained why this is and won't do it again. Anybody who actually flies airways at GA levels knows this anyway; the extreme scarcity of traffic in that height band is quite evident enough.
Slot times do exist but they are merely an artefact of the Eurocontrol computer. They almost always mean nothing in the context of any real bottlenecks. Height capping? I'd love to be height capped to FL200
There should be less aggression in these discussions.
Pprune has a lot wider expertise on it, and a lot fewer nonstop meaningless one-liner generators, than Flyer.co.uk (which is a good thing) but it has a lot more people who behave aggressively (which is very bad).

Very true, but has there ever been "certainty" in this game? I know you have been flying far longer than I have, but I have never seen any stability. Everything is up for grabs, and we pilots (well, anybody who is after anything beyond the simplest UK-only-VFR capability) live a constant paper chase.
Uncertainty is also created deliberately by regulatory bodies. Nobody is going to propose a hard-hitting and extremely controversial regulation in a half hearted manner.
