My point is simply that the foot is a handy length unit to have that doesn't exist in SI. Obviously you can make do without it, but it's something that just works well and if there was a near SI equivalent it would be easier to make the transition. No one seems to use decimeter, which sounds too much like decameter, particularly with all the interesting dialects in the US that would just be a mess. Now if 1 meter was close to 1 foot and then you went in multiples of 10 from there, that would be easier for imperial users to get.
My other point that units that aren't necessarily easy to convert between doesn't matter because the average person doesn't ever actually have to convert you didn't address. It doesn't matter if the system as a whole is better if the only parts that people use regularly are just as good in the old system if it's the average person that you need to convince to use it.
