Not only is md5sum not proven to have equal dostribution, it is specifically known to not have equal distribution, only nearly equal distribution.
A hash function is any function that converts an arbitrary input size into a specific output size deterministically. No other requirements are there. A hash for a simple job could be just adding the ascii values together and give the output. Needless to say, that would not have an even distribution.
The hashes not being there isn't particularly relevant within a hash function outputting a specific size. If your hash function is always 64 bits for example, the fact that you have 3/4th of them not exist means you should be operating as if its a 16 bit hash, not a 64 bit hash. If you still do this math based on the 64 bits outputted (2^64 boxes) you'd arrive at very inaccurate numbers.
This is valid on a single unlisted assumption: The hash function has equal distribution. If your has function ends by multipliying the has value by 4, for example, your number of possible boxes is 1/4th the otherwise expected value based on the size of the hash output
Metabolism can definitely create useful products. Alcohol is formed from yeast metabolising sugars, for example. Same with miso paste. Hell, we can make milk without cows now via precise fermantation.
I was sold a car with a 14% interest rate after being told I wouldnt be charged for interest if I paid it off in the first month, so I could pay it off when my CD popped that week. The bank then told me that I had to wait to pay it off until it "appeared in their systems". Turns out that happened right when interest ticked! Funny how that works
Remember that honey-producing bees are terrible pollenators compared to the specific pollenators who don't produce honey. The honey producing bees being kept by everyone are artifically outcompeting the specific pollenators, which are what we really need to be supporting.

Per Evenwel v. Abbott (2016), even those who cannot vote have a say in policy
"Nonvoters have an important stake in many policy debates and in receiving constituent services. By ensuring that each representative is subject to requests and suggestions from the same number of constituents, total-population apportionment promotes equitable and effective representation."
Undocumented immigrants are also counted im the census, and thus are represented in Congress and the Electoral College. And since they are represented in congress, they are constituents of their congresspeople just the same as citizens or documented immigrants.
Linux? No. Proton, yes, unless they are using kernel-level anticheat like Apex
