I hear you. From what other people are saying elsewhere: they have their volume set for other things - perhaps Zoom calls at work - and don't want to bother moving it in order to watch these videos. That's sorta understandable.

But ofc next they'll want to enable cookies to remember the volume setting across sessions, and then having added cookies, there must be a setting to only optionally store the cookies, and then there has to be the pop-up (pop-down?) banner announcement demanding that before you can interact with the page (well not really but it certainly does manage to call attention to itself) that you make a decision about whether you want to store cookies on that site or not.

I haven't used a media player specific volume control for YEARS on my non-mobile devices. Perhaps bc I have a dedicated button on my keyboard devoted to volume up/down/mute so can adjust it at a moment's notice?

It takes a LOT of effort to be all things to all people. And Loops is new, and looks to be meant for mobile, despite being delivered as a webpage. So if people accessing it via desktop wish that there more features, that is understandable, but it's also understandable to me why those features aren't there yet?
