This company apparently doesn't even produce orbital rockets: https://www.t-minus.nl/post/barracuda-rocket-at-esa-pac-symp...
Their largest in-development rocket is tiny, like a 1/4th the size of New Shepherd? Nowhere is it mentioned what orbital rocket would be launching from this spaceport. Just back of napkin I can't imagine you'll see any orbital payload delivered from this pad by 2030?
The obvious thing for Europe to do would be have ESA fund a replica of NASA's COTS/CCDev/HLS programs, which have overall delivered stunning return on investment and arguably the only reason China isn't absolutely dominating space launches now. This type of token "spaceport to nowhere" pet project is going to deliver absolutely zilch. Ariane 6 is a dead end and there appears to be no plan forward.
