Putting the issue of bespoke frame builds to the side, OTP s/s and fixed bikes are never going to get as popular or as high end as OTP geared road bikes due to the fact that it is far easier for average joe to buy the parts for and assemble his/her own 'custom' ss/fg. There are a lot less components to choose and ensure compatibility between. If you are building a ss/fg you have 1 gear ratio to concern yourself with not 30, you dont have to worry that your shifters have the same activation ratio as your mechs or that your front mech has the correct cage size for your chainrings. If you run a brake its prob gonna be a front brake and the cable routing isn't exactly difficult on that whereas on a geared road bike you'd have 4 cable to route, some of them under bar tape and poss thru frame tubes.
I think if you have made the choice to ride a ss of fg then you are likely to have a bit more in depth relationship with your bike than a high end road bike buyer might have and so you will be more likely to take the time and effort to assemble your own bike.
Plus fashion is a big part of the fixed scene (no matter how much you all deny it it is) so buyers are less likely to be happy with the colour coordinating or particular component choices on an OTP bike.
