The 1,000,000th guitar is a benchmark, in their museum a lot of people get to see it, not just one private owner, it's meant to be a showcase for some of their artistic inlay work.
There are 999,999 other guitars (up to that point less attrition) for folks to play, it's not like there's a shortage of Martins.
I understand why they made it a showpiece, it's a commemorative not a players guitar. Martin also has 50 D-100's slotted for the numbers 1,000,001 to 1,00,0051. They too are highly "adorned" and most will end up in humidified glass cases by wealthy Martin fans, most of which also have a stable of Martin guitars they actually love and play.
Nothing wrong to me of making a guitar to commemorate an anniversary/landmark with the intent to put it in their museum to
be shared. Martin is very good to their employees who are also allowed to build one guitar for themselves (or one a year?).
Commemorative guitars are no big deal one way or another to me..........
