Mike,
Have you read any of the proposed (and existing) legislation? Virtually NONE of it deals with quality control, or making vaping products more accessible to smokers; in fact it does exactly the opposite. And the proposed FDA deeming regs will virtually eliminate access to vaping products, meaning that the "common smoker" will not be able to be informed about vaping products, will not be able to get them, and will be left with only the pharmaceutical "solutions" that cost more than smoking, and don't work.
For liquids, there are many many good sources out there. If you have been buying "poor locally-made juice" what kind of regulation do you think would help? Flavor police? Regulations would definitely solve the juice problem, because you wouldn't be able to taste samples before you buy, you wouldn't be able to buy DIY supplies, you wouldn't be able to buy anything off the internet, so the poorly-made local juice, bought blind, would be your only option, if you could find any.
And "Cheap Chinese hardware"? Yes, it's available. And lots of it is not only cheap, but also of good quality. Not all of it. But nobody is forcing you to buy chinese hardware, and nobody is blocking the reviews and discussions of it, and nobody (at the moment) is preventing you from buying the hardware you decide you want, based on an informed decision. Regulations will change all that.
Can you name a single regulation (on anything) that ensures that what you're getting is "not junk"? People buy crappy cars, houses, TV's, tools, appliances, food, etc. etc. etc. The only legal protection you get for most anything you buy comes from laws about warranties, and that law applies to pretty much everything.
If you want your government to make you safe and happy, you really should think it over again, and perhaps read some Thomas Jefferson.
