You seem confused.
You bought a plot of land, presumably with a house on it.
You didn't buy a lifestyle. You don't have a deed to a lifestyle, you have a deed to land and a house.
You very much did not buy your neighbor's land. So if your neighbor wants to build some dense housing, what on Earth makes you think you have the right to stop her?
Now you may have the power to say "yep, not in my back yard! I'm going to file a bunch of stop orders and vote for politicians who are hostile to upzoning (and who happen to own some property whose sticker price they're afraid of disturbing)!"
The reason I consider this desire invalid is because it isn't your land. What you're doing is abusing zoning, which is supposed to keep factories away from human habitation, to prevent other property owners from building the kind of housing they want on their own property.
I've decided that I'm glad you consider NIMBY an insult, you NIMBY. Your kind deserve to be insulted, and those of us who think it's disgusting to tell a productive citizen of our cities "move away if you can't afford an apartment" plan to defeat you and get back to building.
> The attitude of feeling like you are owed great housing in a great location at a great price feels like entitlement to me.
Have a look in the mirror, NIMBY.
