So for violin it is much harder only because the basic techniques on violin are harder. DIFFERENT (MT)

No, it's almost universally accepted that they are harder. Advanced techniques maybe the reverse is true, but to make an acceptably good noise, it is harder on violin.
Yes it is harder to make a single note on a Violin. There is a bigger hurdle to making a tolerably listenable-to sound. No argument.
But on piano simply striking a note any-old-how and thereby making an acceptable sound - in my book that hardly qualifies as "technique" at all.
And anyone that thinks that learning to play a sequence of notes (e.g. a scale) on piano with absolutely precise timing and gradation of tone is comparatively easy has either never tried, or is easily satisified, or has vastly more talent than I can conceive.
What's more some so-called "advanced" techniques on piano are really rather basic.
For example: On piano you can play a four-note chord and make any note stand out. You can play it four times in succession and create the sound of an arpeggio. Is that an "advanced" technique? Not really. It is (a lot) easier than playing a scale in true legato with a nicely graded crescendo and diminuendo.
I'd guess it takes a similar level of control to making a single good sounding tone on a violin.
