That's because of a crack down on cheap lithium batteries. You can blame China for it. They keep catching fire at random times, even when not being charged. And it's been getting worse, especially with smaller devices. Like sex toys. They really don't care about your toys, but you really should check them because of the battery.

Yes - you understand perfectly what I am describing. Below is an image that roughly shows the intended setup. The blue line represents the hollow 'stent'. You can see that it terminates outside the bladder and internal sphincter. It stents the external sphincter open. The end result is a filling bladder then autonomous emptying in an unpredictable way and not constant dripping.  Bear in mind that the 'stent' could be a Foley or Nelaton with the end chopped off, or a silicone sound. Also note that there is no external 'stopper' shown in the diagram. The diagram just illustrates the general principle of operation. The stent itself could be much truncated to terminate in the urethra at a position roughly where the base of the penis begins - it need not terminate externally. Having a short one would remove the external infection risk and would mean nothing visible externally. But the tradeoff is difficulty of positioning and retaining exact position, and maybe other problems. There is no 'plug' in my idea. The body keeps it 'plugged' by the internal sphincter until PMC activation and normal micturition. I'd imagine that this behaviour is EXACTLY the same behaviour as a pre-potty training infant - urine builds, body naturally voids periodically. The difference being that the infant does not know to use the external sphincter, whereas that adult with a stent cannot use it. The only real problem I see with this is that the internal open end (or the holes in a modified catheter) may be obstructed  simply because the urethra is 'squishy' and could kind of collapse and inadvertently plug that end.  

This exactly! I always point out that "a thin diaper that has leaked is WAY more noticable than a thick on that has done its job". And I've told plenty of medical professionals the same thing. By not calling them diapers they are adding to the stigma and only confusing exactly which product you're talking about.

Legal just means expensive. I live in Florida and more than qualify to get medical marijuana dispensed. It costs $300 for a yearly evaluation and buy-in license. Another $75 in state taxes. And roughly another $300/month for a medium-use dispensation.  You can expect a total of about $4K per year for normal use. Very light users can get by at about $1K, with chronic users costing upwards of $10K per year.

I have to agree with this assesment. ATN is the bare minimum for a functional diaper. As long as you're staying well hydrated they will only last 2-3 hours with a near constant dribbling. Or 1 full bladder void at most. However, if you're using them 24/7 then they are not the cheapest diaper out there, nor are they very effective against embarassing leaks. Diapers like Betterdry and Megamax are better for that. But as a starter or emergency diaper, they can hold you over long enough tillnyou can get a better diaper. Just don't try using them overnight, they are no good for that, despite the name.
