Why does my icloud drive say there is not enough disk space when i really have 1.7 TB available (continued)

i recently purchased the 2 TB iCloud drive option and am copying files from an external HDD. The files total about 200GB+ thus far. I am having a nuber of issues with this service and require clarification.

1. the files have been in the uploading status for approx two days and little to no forward progress has transpired in getting them into icloud drive.i have read numerous help articles which have mentioned checking internet connection speed (yeah ok got it). but my logical response to that is i can stream and surf from numerous devices in my house at once with no problem. So basically i feel that the internet speed is not the problem.

I have read other help articles which have stated that i need to have enough space available on my local HDD to accomodate the system boot file to be transferred. To me this sounds counterintuitive to the purpose of having an online file service such as icloud drive.
