You're not going to get people to give your idea due consideration when you start off your post with irrelevant ranting.
Removal of HQ materials doesn't make gil meaningless.
Removal of HQ materials has nothing to do with the housing situation.
With a player base that demand HQ gear and consumables, it's pointless to say "but NPC vendors sell NQ versions of those things with inflated prices" because players still aren't going to want to buy the NQ versions if HQ can be crafted or obtained through quest rewards.
As for your idea, it's interesting though I'd say the charged Crystal generated should be used specifically for ALC/CUL consumables, with the ALC consumables applied to gear to give the glow effect/other property on a temporary basis. If the effect needs to be refreshed, it would drive up demand for the consumables and thereby increase the value of the charged crystal. It would also allow them to be applied to the tomestone/dungeon/trial/raid gear.
HQ crafting is not being removed. They stressed multiple times in the exact sources you mention that it is only affected gathered materials. Intermediate crafts (ingots, lumber, etc.) and final products can still be crafted as HQ.
A competent crafter with up to date gear needs no HQ gathered materials to create a HQ item. It's easy enough to HQ the intermediate crafts for Exarchic to get HQ on the gear.
The only reason most crafters would buy HQ gathered materials is because it was the cheapest way to get the quantity they needed. That's part of why HQ gathered materials were an easy target for removal by the developers - they could see that crafters were generally ignoring them.
HQ didn't do anything to make gathering feel more interesting to me (probably because I was always gathering for yield not quality unless HQ was needed for a gathering class quest).
Rating (which is essentially a form of quality) will still mean something when doing collectables. I expect the system to remain the same so we'll always want to hit 1000 to get guaranteed aethersands so that's something.
I wish SE would consider bringing back Hidden items. Those could have been a good replacement for HQ - as long as they stayed out of the job quests and the hidden items used to craft vanity items like cosmetic gear, minions, furnishings, etc.
