There are still many non-scarce things you can spend your extra money on.
An example of what you can do: buying expensive cars.
An example of what you can't do: buying up land so that everybody else has to pay higher prices for housing.
if they are non-scarce, then you already have obtained your required amount, and thus no longer demand more.
> buying up land so that everybody else has to pay higher prices for housing.
buying up assets, since assets would be scarce, allows you to demand payment for their use, and thus, ensure your future financial situation is secure.
It sucks for those who don't own assets, but this system resolves the conflict of how to assign assets amongst people. And it gives those who don't own assets the motivation to work harder. The resulting society will then have more aggregate wealth than before.
It sounds like we can assign bandwidth to the highest bidder then. Who needs Net Neutrality?
Seriously, the problem with your thinking is that you're stuck with the idea that our current economy is the only and most fair way to divide resources.
Your assumption here is that you can trade human work hours for finite natural resources on some market, and that everyone has to pay for those resources on the market. There is nor reason why you should be able to do that, rather the natural system is to allocate all finite resources equally to each person and then you an pay for those with your work, but you working harder to pay a person to share his resources with you wouldn't affect anyone else in the economy unless they too wants to have extra of that resource.
What if no one wants that 1 hour of labor? What if more people want 1 hour of a certain type of labor that exceeds the supply of that certain type of labor?
Doesn't have to be hours, the hour was just to represent that it is a human working and not a finite resource. Different human work can be valued differently.
The fact that it is expensive is what defines it as scare (i.e. lots of demand relative to little supply).
How about using a less fuel efficient vehicle? Is that “against others” as it uses up the non polluted portion of the environment?

Land is not the same everywhere. Low humidity, Mediterranean climate, coast California views are extremely scarce and in high demand. How are you going to fit 8B people onto the world’s desirable land?
If you want better than median living conditions then you work for it. There is no reason why it should be free to live in the best parts of the world if not everyone can, otherwise the privilege of living there would be a source of injustice.
It is true that if you want a luxury resource, like a very attractive location to live in, then others working more for that position means you also would have to work harder if you want to have it. But I don't consider people competing for luxury resources a problem, no that is a feature and is what makes the economy tick. If you don't want that rat race you have to live in median conditions.
>An example of what you can do: buying expensive cars.
Why are expensive cars not scarce? They're ultimately built using scarce resources (eg. steel, rubber, plastic, labor).
At some point, that reward is going to be traded for something else that's in demand and where the demand exceeds the supply. If you interpret that as "use their extra earned money against the rest of us", then it seems that you are going to have to disallow the notion of rewarding those who decide to work more than average.
The voters do. People vote for corrupt politicians since they care about other things. They would do that even if you didn't have capitalism. The problem is therefore the implementation of your democracy and not capitalism. Removing capitalism while keeping the flawed democracy would just result in another Soviet scenario or even worse.
So the problem isn't capitalism, it is corrupt democracy. A corrupt democracy will try to do whatever it can to enrich its politicians, like taking bribes from companies etc. A healthy democracy doesn't take those bribes. You can find many countries where politicians works mostly for the people and not for companies, that is how it should be.
Keep going down the rabbit hole and the problem is corrupt humans. Transparency to enable everyone to keep everyone else in check is the only solution I can see.
However, those people should not be able to use their extra earned money against the rest of us, who made different life choices.
