I have frontal diffuse thinning, is hair transplant a viable option for me? (Photos)

I’m 34 and have frontal diffuse thinning since my late 20’s. I'm on 1mg Fin for a year, with no sides. No regrowth, but I feel my scalp is healthier. I'm considering a HT. My goal is to restore density. I met a doc who is part of the IAHRS; he advises against FUE for a first time HT even though he does it and has ARTAS. Says a 2000 graft FUT to restore my hairline and some density. Is that too much or too less? I am also worried about the linear scar, stretching, and permanent shockless, etc.
