right?

lol: my bad; um, no:

that's what open position chords are for!
(among other things)

Csus2 for example:

I can easily fret

e|--3-----------> G (12th scale degree added for the win)
B|--3-----------> D (optional 9th
G|--O-----------> G (5th
D|--O-----------> D (2nd
A|--3------------> C (root)
E|--X--------------
