Recently, Wang with Stankiewicz (Phys. Lett. B 800 (2020) 135106) opposed thewidespread belief that due to quantization, the Big Bang singularity {\em must}necessarily get smeared and replaced by a non-singular "Big Bounce" process.Their claim is supported in a methodically independent manner in which just ahighly schematic model (viz., the discrete and drastically simplifiedWheeler-DeWitt equation) is considered. Our comparatively elementaryargumentation is constructive, based on the assumption that the evolution ofthe Universe can fully consistently be described using an innovative, hiddenlyHermitian version of quantum theory formulated in a properly upgraded Dirac'sinteraction picture.
