Does it makes sense to build a "space tower" in Indonesia and Brazil?

I wanted to make a setting that has a "space tower" of some kind, not necessarily a space elevator (it might be a fountain for example, or even just a gigantic upward pointing mass driver).

It makes sense to build them in the equator. Also, I wanted to avoid building on water.

Also I have this notion, that maybe people would want to build at least two of them in opposite places, so they could eventually build a ring around earth to accelerate spacecrafts for launch.

Thinking of all that, I concluded that people might want to build the pair using Brazil and Indonesia, the two countries are crossed by the equator, they are exact opposite of each other in the globe, and both have large populations that could support building such launch tower (even if their governments aren't willing to finance the construction).

So, did I missed anything important, there is anything that makes this a bad idea, or ultimately, it does make sense to build space towers in Indonesia and Brazil?
