Its more than just "can we do it", its also "does it make sense". If you are doing a limited number of missions, it doesnt particularly make sense to go reusable, because you're going to have a hell of a time getting suppliers. If you are going to do 6 launches a year, and you can do that with 2 rockets, then you might think to build 4 rockets total. If youre developing your own engines, you now have to spend all that money to build maybe 4-16 total engines, depending on the design, which means your per engine cost is going to be massive. Same with core stages and everything else. You end up paying massive costs per component, and now you have to figure out what to do with those production lines you just started. Do you keep working on making more engines? Do you shut down the line because you've made enough for your 4 rockets? That, combined with a lot of reliance on solid rocket boosters, which are less important to make reusable, makes the idea sketchy. If we needed to put tons of stuff into LEO 30 years ago, the projects probably wouldve been attempted before. We just didnt really have the launch cadence to support it
