But I wouldn't want to try that for a regular commute where it's also expected that I put in a good 8 hrs/day at the job and all the normal at home chores in the evenings.
No, it's not equivalent. It's not meant to be equivalent.
My advice is to build up to a 100 km ride ... which the OP has not done yet ... and then try a back-to-back 100 km and see how happy he is to get up the second day and ride another 100 km. If that's a bit of a struggle, then perhaps he might reconsider the 100 km/day commute idea. At least until he's fitter.
The longest ride the OP has done so far is 30 km. First he needs to actually ride a 100 km then two in a row before he can even
begin to judge whether this is doable for him.
