Yes, there are entrenched interests, far more then just billionaires, that are always prefer the status quo. But its also wrong to say that the status quo only exist to serve those interests. Rather that the those players have best adopted to the status quo best.
Wallmarkt is perfectly adopt to US idiotic zoning and land use strategy, but its not Wallmarkt lobbying that created that strategy. Its the other way around.
And all known good changes have to overcome entrenched interested. And just standing around saying 'nothing can every change because billionaires' is silly.
Other countries that have walkable streets have billionaires, there are very highly profitable shops and properties on those streets that billionaires can and want to invest in too.
I would say that implementation of land value tax would generally help billionaires as well, because it just overall more efficient. That is the problem with the far left, if you see everything always as only a class war and specifically in the modern sense where its the 99.9% against the 0.1%, you miss that there are many other entrenched interest that matter a whole lot for deciding where society goes. Those can even be reasonably poor people.
You are not wrong that 0.01% of the population matter but interpret society only as their tool is missing a much bigger much more complex picture.
