"While the general form of the argument involving a slippery slope is not valid, the conclusion it leads to is not necessarily wrong."
Slippery slope is one of the few "logical fallacies" that can be used, if applied correctly.
For example, Alcohol.
If I were to say "They should not be able to ban driving while drunk, because they won't stop. Next they'll just flat out ban alcohol."
It would be a valid argument because alcohol was, in fact, banned before.
That's actually an example of the fallacious kind of slippery slope there, good work.
It 'can' be a valid argument, but not in any of the cases you've used it in.
The heart of the slippery slope fallacy lies in abusing the intuitively appreciable transitivity of implication, claiming that A lead to B, B leads to C, C leads to D and so on, until one finally claims that A leads to Z. While this is formally valid when the premises are taken as a given, each of those contingencies needs to be factually established before the relevant conclusion can be drawn. Slippery slopes occur when this is not done -- an argument that supports the relevant premises is not fallacious and thus isn't a slippery slope in technical definition of the term.
