You'd be surprised, especially on sloping ground how easy it is to be a few degrees out by eye.
In FT sitting you're in a stable position and it's the work of a second to glance at the level to check. As above it's quite an eye opener sometimes when you think the rifle is level and the bubble is way over one side. I like to set the bubble so I can see it in the field of vision of the non-aiming eye so I don't even need to come out of the aim.
A 5 degree cant will cause a 1" shift of POI at 50 yards. Yes of course on flat ground you'd spot 5 degrees a mile off but in a wood, when the ground is undulating, you can't see the horizon, when your shooting position is on a slope and your target isn't on the same level as you it's a lot harder. Very easy to deceive the eye.

Sure, Benchrest, Prone, and FT - I kninda forgot about FT. But yes, anything when you are stable, and can afford to glance at the scope with upsetting anything, or your quarry running off, I do understand the consistency "angle".
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
If you think you know far better, fine, but I think you know very little to nothing about levelling. The first consideration in a level is, is it accurate and does it have a kitemark and comply with the current British Standards for levels, if they dont, and I am sure that will be the case with these cheap examples then they are worthless. Scope levels made by the companies you mention are like fishing floats, many made to catch the angler who is daft enough to buy them rather than the fish. It does not matter how many levels you affix to a gun, there is no way of knowing the gun is truly sat level in the stock so anything attached to the gun or scope will potentially give a point of reference but not one that is truly level.
I could not have said it better myself
We can only do what we can only do, there will always be limitations in our equipment, but we can only try our best to do the best we can with what we've got. I'm not a level expert, clearly you are, so if you can offer us all a cheap and workable solution, which can be demonstrated to offer significant gains from what we currently use, then I'd love to have your input

Buy a plumbob and line. Most competition shooters will have already set their scopes up with a plumbline. I am not a level expert although I have had over 50 years of experience using all sorts of levels some costing many thousands of pounds with none as basically crap as the ones offered to the gullible for so-called rifle levels.
To me, personally, it's not really about scope reticule being perfectly horizontal - it's about consistency. If I am canting slightly I want to cant slightly consistently. I only shoot 50M paper targets these days so cross-over isn't a problem and yes, sometimes the targets aren't perfectly square in their holders but with the use of a scope mounted spirit level (checked with my nonshooting eye) my rifle is held consistent for each and every shot.

One more reason to use BKL mounts. I have a spot on the countertop that's perfectly level and I sit my BKL mount on this spot. I then put the scope in the rings and use a small level on the scope turret. I've already mocked up the scope for eye relief, so I know where to place it in the mount. I know it's not always dead perfect, but it's always very close.🙂

I have always set the scope up using a plumb line.
Very accurate if used correctly.
I never use a level on my scopes, but only because i dont feel the need.
On the other habnd though I see so many shooters canting the rifle, so a level would help them.
A "cant" at fixed range is fine but if you shoot a varying ranges then a "cant" is bad for accuracy.
Depends on the individual, if they help then use them.
