ironically, that's what most people do. but even if they're not stuff like that gets tracked via gyro and interpolation - it doesn't really matter where exactly you press the button behind your shoulder or on your hip, just that you do and the game reacts accordingly.
don't get me wrong, I'm certainly no fan of outside-in tracking since it adds a retarded layer of image processing on top, not to mention the potential security issues, but lot of the problems from the early days have been figured out by now or get worked around - also one of the reasons I'll forever shit on gabe since he could've pushed lightroom a bit more and made it the standard or go to solution people want, especially since it's more work to convince normies to set shit up, getting them to use an HMD is already annoying enough. also lead to games focusing on the quest with their hand tracking or index' knuckles, which means they're an absolute bitch to play anywhere else since you will smash your controllers together constantly.
it is - but in actual 3d, meaning you can look around stuff and have a little mouse do things. VR was never able to be sword art online, mainly an enhancement for certain applications that profit from a proper third dimension, that's why anyone going MUH FAD already missed the point since that extends beyond
kids toys video games.
since the boom imploded your only options are valve index, getting zucc'd or reverb G2 (WMR, so no linux support). you could probably also get your hands on some used stuff, but you never know how it has been (miss)handled. there's some stuff like pimax or pico, which all come with their own drawbacks (for example the pico is standalone like the quest, so you're potentially paying for shit you don't need, and made by bytedance, who runs tiktok).
if you really just want to check it out look for a used WMR like lenovo explorer or odyssey, shouldn't be that expensive these days and they were common enough to still get your hands on replacement parts somewhere if necessary.
ironically PSVR was also a great option if you had a ps4 pro, you could get it for the same price as the entry WMR sets with much less of a hassle and you could even keep using your dualshock since the light bar was made for tracking (not even PC can do that without hacks). PSVR2 could be great, but it's way more expensive and since it's limited to console has access to a way smaller library, and only the stuff sony allows. it also had one of the best VR exclusives (before disney shat the bed and squadrons tried way too hard);
