If I'm using purge to remove something, will I be able to reinstall that thing after if I want or it's somehow blocks that option in the future?

You will be able to install the software again in the future.
purge, except from the application files, removes the configuration files used by that application as well.

You will be able to install it normally. The only difference between purge and regular remove is that purge destroys your settings. So if you reinstall, your previous settings will be lost.
