Inscriptions and ordinals are potentially zero day exploits wrapped in colorful memes.

They are not, because the blocks are valid 🤷🏼‍♂️
Congress passes bloated pork bills filled with graft and largesse which are also “valid” according to Constitutional protocols.
You’re missing the forest for the trees. 🌳
My node will never block valid transactions!
But I wish you lots of fun patronizing others on how they should use Bitcoin.
Projecting accusations onto others what your original message actually commits is a red herring nor does it change reality.
“Valid” is logic (rule-based model) and is not necessarily synonymous with effective or true when applied to reality.
Greeks entering Troy’s gates via a wooden horse or Mongols bribing Jin guards to open gates to the Great Wall of China were also valid given neither violated the laws of physics.
I find it extremely funny how a few individuals try to decide how others should use Bitcoin.
The irony is that a few individuals charged with spearheading freedom through decentralization (i.e. Bitcoin Core) seek to undermine it by mandating how others use their personal Bitcoin nodes; i.e. removing their OP_Return limit options.
In essence, Core is mulcting Bitcoin nodes as game theory or indirect pressure to centralize, control, and destroy Bitcoin which happens to be the only bulwark between you and a totalitarian state.
Bitcoin blockchain bloat is a shelling point for centralization and control.
The real irony is Bitcoin Core falling victim to Control Paradox.
You clearly still haven’t understood that the limit should be removed because it is completely irrelevant! It has always been possible to mine arbitrarily large transactions directly or to send them to a miner. So the limit is completely pointless since it has no effect.
And the argument that the blockchain gets bloated is also nonsense, because you can simply prune the data.
Imagine I’m Tom Cruise and you’re Jack Nicholson in the movie “A Few Good Men” (1992).
I proceed to ask you a simple question while you’re under oath as follows:
“If the OP_RETURN spam limit is as irrelevant as you say then why has Core risked all their political capital and the potential ossification of Bitcoin to have it removed?”

Whatever actually "is" an ordinal? An ordinal is not a thing.
An 'ordinal' is just an arbitrary made-up numbering system for 'numbering' Satoshis.
And an "inscription" is just a made-up blob of arbitrary data that can be artificially "sold" (but not really) by pretending that ordinals exist.
I "give" you the "numbered sat" and we "pretend" that you "own" that blob without necessarily owning any more *actual* Bitcoin.
That's all that 'ordinals' are. It's like numbering clouds.
“”Whatever actually is a Bitcoin? A Bitcoin is not a thing. It is just an arbitrary blob of data used for transactions…””🤦‍♂️
Adjust your paradigm to a level of abstraction that favors utility.
Employing Wittgenstein semantical arguments is nonproductive.
