-play at super low resolutions to get good refresh rates
Doesn't matter, XGA+ / SXGA were often used with 200hz 0ms.
How do you not consider 1024×768 or 1280 x 1024 to be a low resolution? That's between 38% and 63% the pixel count of 1080p and 1080p is already a low resolution by modern standards.
You can even affort HD+/FHD but screen is shrinked due to how CRT is builded and still get higher refresh rate and lower reaction time than any LCD
This is 100% wrong. You can get LCDs today that are 240Hz at 1080p and use backlight strobing to have essentially zero motion blur. Go find me a CRT that displays 240Hz or more at a resolution substantially greater than 640x480. Hell, I have a monitor (XL2720Z) that is "only" 144Hz with backlight strobing and I can't really detect much of, if any, motion blur at all.
-have inferior image quality in every way aside from motion blur/refresh rate
Not even gonna comment

Only thing what I will tell is that CRT is not limited to CMYK/RGB color palette and doesn't have contrast limitation which allows FAAAR better black+white contrasting than ANY newest LCD/Plasma.
Okay, I concede that CRTs
can have better color than LCDs, if you can find one in proper condition that is still functioning like new after 20 years of use. But is that really relevant to our situation here? I don't play osu! to marvel at colors. You know what is relevant? They are not anywhere near as sharp as LCD monitors, especially at the resolutions you'll be playing at to get high refresh rates. I hope you don't have to, like, read text or anything on your fullscreen 640x480 blur.
-don't mind playing on a tiny screen size
Last gaming CRT monitors were 28-32", if you call it tiny screen...
1. Good luck finding one available for a reasonable price.
2. Have fun getting it shipped to your house. Bet it won't be expensive to ship something that weighs 200 pounds.
3. Hope you'll never have to move it anywhere for the rest of your life. I had to have four of my friends carry mine to get it up a flight of stairs.
4. I bet sub-HD resolution will look awesome on a 32'' monitor, even without a native resolution. I bet the dots will be the size of postage stamps.
Here's the real meat of the situation, though - all your arguments are at the theoretical level which mean precisely dick. The reality:
1. A CRT that has all of these awesome ideal specs you are ratting off will be incredibly difficult if not impossible to find in 2017.
2. If you want to try to find one, you'll have to do a ton of research on CRTs and CRT models, and search all over the place all the time for the ones you want - all around, an enormous, time consuming hassle.
3. If you manage to find one
(in decent condition, these are old!), it will be
prohibitively expensive to buy and ship.
4. If it ever has an issue, or its pre-existing conditions worsen, you are fucked because almost nobody repairs these things anymore and you will get yourself killed playing with high voltages fixing it yourself.
Why go through all of that when you can just buy a decent new 144Hz+ gaming monitor with backlight strobing, have equivalent or better performance, spend less money, have something that is enjoyable to use for anything other than gaming/graphic design, have a warranty if something is wrong with it, and be done with it?
The only reasons anyone should buy a CRT today are
1. if you can find some random passable one for cheap in your local area at a garage sale or flea market or charity shop
2) if you have tons of money to burn and can find/afford one of the rare ones that compete with today's best LCD monitors.
Oh, while I'm here and I have your attention - I passed you on the leaderboard yesterday. Suck it.
