That is absolutely wrong. The law is clear on this point.
Law 45 C. Compulsory Play of Card
1. A defender’s card held so that it is possible for his partner
to see its face must be played to the current trick (if the
defender has already made a legal play to the current trick,
see Law 45E).
2. Declarer must play a card from his hand if it is
(a) held face up, touching or nearly touching the table; or
(b) maintained in such a position as to indicate that it has
been played.

It certainly may if it is held by a defender. It might if it is
held by declarer.

It applies only to the opening lead.

Sure, but he needn't use that indirect method. It's much easier
just to say aloud: "Please play a spade, partner."

That might be an interesting game, but most of the time would be
spent debating whether a card had been touched or not, and the
play of the cards would be sort of random when unwanted cards
were forced to be played.
This is a cure that is worse than the (nonexisting) disease.
> just as touching a bidding card in the box must not be altered.
This would depend on the region (it's not law), but I have yet to
hear about one that insists on a bid being made with just a
touch. Under Danish rules the bid is made if the card is pulled
out of the box - where TD has to decide how far.

Why not go the whole nine yards: Never make mistakes!
