And you physically cannot get a piano tuned perfectly, since with different intervals, you'd need individual notes to be tuned slightly different.

With a guitar, you can at least still try to correct it by putting your finger down somewhat closer or farther away.

Does not work like that. It isn't a violin.

It is possible to pull notes sharp slightly (but it's done with pressure, not finger placement), but if the note is already sharp, there's nothing you can do.

Move one fret flat and pull very sharp? (no, this is not practical, but the inexperienced should give it a try...)
