There are plenty of bases built for obvious utility, like this Gamma Weed farm which glows pleasantly at night.
In a nice stroke of Fully Automated Luxury Communism game design, harvesting crops is entirely client-side (separate copies of a given plant in each player's game) so building a farm is like opening a giant free buffet to all visitors. It's not uncommon to find notes of gratitude left by visitors.
It is nice to exist within a community with such values.
