can you say anything that really go against my statement?
I'm not the person that you originally responded to, and I can't tell if you're trolling, but here are some responses to your statement.
I believe Spikes should be banned. It is able to do enormous damage.
I agree that Spikes can do big damage, but:
1. They only affect grounded Pokemon (disregarding Boots), and those without Magic Guard (although that's not relevant in the current meta).
2. Doing 12.5% with one layer up is good, consistent chip, but if something is holding Lefties, it's only two rounds of Leftovers away from negating Spikes damage. I also wouldn't consider 1/8 to be "enormous damage" because something like regular Poison or Salt Cure against a non Water or Steel type does that every turn, and it's not like people look at one round of that amount of damage the same way that they do Specs Lele in SM or anything.
3. Getting up multiple layers of Spikes is difficult and usually if someone is able to get and keep up three layers or something throughout a game, they probably just won the game handily anyway.
It is impossible to remove them.
This is hyperbole - it's not impossible to remove hazards. Sure, Gholdengo makes it so that Corviknight can't Defog, but that doesn't mean that dynamic alone makes it "impossible to remove" Spikes. Gholdengo isn't a guaranteed way to prevent Spin from Tusk or Treads either, since Gholdengo can't freely switch into Knock or EQ from them (unless it's on a Balloon, but Knock is very common on Tusk and Treads anyway and it can be difficult for Gholdengo to keep its Balloon in tact). I honestly feel like it's easier to remove hazards in SV then it was in Gens 4-6, and I could even see a case being made that it's harder to keep hazards up in GSC and ADV as well, although I don't really play those tiers.
A PROOF IT'S CENTRALISING: ALL POKEMON OF OU can use Heavy-Duty Boots.
Every Pokemon can hold a Utility Umbrella - does that mean that Rain and Sun are overcentralizing? I personally dislike Boots a lot, but I think it's a fallacy to say that since every Pokemon can use it, hazards are overly centralizing. Unless you mean that every Pokemon can benefit from Boots, which sure, that's true, but you can say that about almost any item. Everything can benefit from Leftovers, but something like Iron Valiant probably won't run Lefties since it benefits more from other items. Similarly, you won't see Garchomp running Boots because they don't help it nearly as much as something like Leftovers or Helmet does. Boots are also less common in SV than SS anyway, although I feel like they'll probably pick up in usage in time. It's also odd to me that you claim that Boots are proof that Spikes should be banned, since the fact that Boots exist means that there is a method of completely invalidating hazards. And again, I really dislike Boots and would prefer it if they were never introduced so that hazards could be even more impactful on the meta, but I'm also an SM player and I understand that views differ on this. Either way, Spikes and Stealth Rock are extremely powerful and hazards have completely shaped competitive play since GSC, but I think they're positive aspects of Pokemon and shouldn't in any way be considered for a ban.
