something to keep in mind is that this item probably wouldn't stop someone from falling behind or completely negate them getting pressured in their lane etc.
in fact, buying an item like this instead of putting souls towards something that could boost your stats in a more meaningful way would almost never be ideal and would usually cause them to fall further behind in some capacity
it could occupy a similar role to other early items like
Monster Rounds,
Healing Rite and
Reactive Barrier-
those aren't items that you would want to buy on most heroes when there's items with better stats available for the same price, but they're still useful options if you get forced into a certain situation in the lane
Counterpoint... first thing-

Your minions spawn at the same rate as their minions do. Whether you're pushed to your guardian or you're pushing to their guardian is only subjective in the amount of damage each guardian takes; otherwise, there's the SAME AMOUNT OF SOULS YOU CAN GET FROM SECURES OR DENIES.

Tradeoff. If you suck at securing souls, make them harder to secure for your enemy. If you secure them instantly outright, then that just becomes actually unfair to the enemy; if they have the higher skill level TO deny your souls, they should be able to. More skill should always beat less skill; it's how labor markets in economics should be as well, though we know how crony oligopolies have become (but that's a political discussion I'll refrain from in this forum.)
Point is, it can also get better stats as well. Maybe +2 HP/s, which is a good chunk of regen compared to other early-game items; and very few items provide even 100 HP in the early game; that's almost +20% HP on base/beginning units.

MR doesn't help in securing souls, it only provides minor clearing and defense potential. Realistically, it just makes it easier to pursue ENEMY HEROES through their own troops because you take less damage to the troops and therefore have more health to engage the ENEMY HERO with. As well, so what if you kill a minion faster or with less shots? Enemy steals your souls, and it's half gone anyway. Same problem above, you CAN'T just outright instant-deny a chance, as that doesn't allow skill to flourish. The increased speed and decreased timer at the sacrifice of spending souls on that item is exactly the same as the ultimately weaker stats from MR which is ALSO horrible past your first walker.
HR pretty much requires you to be out of an engagement, as one damage from an enemy hero and poof! Healing gone. It is also slow and requires you to be out of combat for 10-15 seconds or so. So, when you do kill a person in your lane, you'll STILL have to retreat as their respawn and zipline time could cut your healing short if they hit you before the end of it. Skill-based item; sacrifice combat and lane for the need to not go back to base... and if you killed the enemy at your guardian it's only a second or two slower to return to base and NOT waste the money on HR.
RB is conditional based on the unit you're fighting; so I don't get what that has to do with souls. It is a good counter item though; and it does address your point. Just, insta-securing souls isn't the same as preventing stunlock characters from getting the significant upper hand.
still useful options if you get forced into a certain situation in the lane
Want to know what else is useful in certain situations in the lane?
1. Backing up.
2. Asking to swap with a teammate.
3. Focusing less on damaging the enemy and instead focus on hitting their souls.
4. Staying on high-ground and staying away from the enemy as much as possible.
5. Don't panic if you get hit. If you're low, retreat and let them get some ground.
6. If you can't push, hide behind your guardian and secure/deny souls from there.
7. Getting ganked? Just give up the lane, and either farm boxes that have probably spawned around the map or try a hand at some T2 jungles or soul slots. Losing a guardian and even a walker at minute 10 isn't the end of the world. Being 20k points as a team behind their team at minute 10 is probably the end of the world.
Not a single one of these requires an item to secure souls. In fact, many just tell you to leave or not care about fighting. Will your stats be a bit lower? Yes. Will you be safer and compensate for the lack of skill necessary to consistently hit headshots and pursue opponents? Also yes.
