Is Emergency Build useless?

[Gimboid]

If i have colonised planets earlier then you who developed slower then i will also have built up the infrastructure on those worlds to

My economy and research potential is bigger then yours by turn 20, and i can have my planets fully outfitted (with max facilities on each planet allowed) and producing WP, ships, whatever but also since those planets are fully outfitted they dont cost me minerals to develop anymore and i can divert those minerals to other uses like further expansion or ship production.

Therefore my entire empire is bigger then yours and has a lead in several areas faster by expanding this way.

The risk u mentioned is only slight, people using this strategy usually have space base yards built before emergency build wears off so they still have great potential to build ships to defend themselves. They can also retrofit the bases to have weapons to defend the homeworld...

Overall i'd say the risk is minimal because my production capacity far exceeds a player who doesnt do that, their one frigate is only an annoyance not the end of my civilisation
