Progress comes from all sorts of places. Scientific progress come from scientists. That doesn't result in things better in my life without a huge number of other people doing things well and efficiently. Both of which includes anything people will pay for, including b2b saas apps. Try having a pandemic lockdown without Amazon-level fulfillment in place. Thankfully we didn't have to.
Who would you like to appoint as an arbiter for what "valuable work is"? If certain people enjoy and pay women to fart in their faces - would you like to ban that? How about other "useless" activities that humans enjoy like video games or massages or fashion or fancy restaurants - would you like to ban those as well?
Depends entirely upon the quality of the fart.
