Why is touring as a band so hard right now?

I built some tour management software for DJs but increasingly all our users are bands who are switching from master tour / daysheets to save $ so I'm curious what's changed / what's making it so hard now vs a decade ago?

I'd love to keep building out tools for smaller bands/artists but very much not my scene.

edit: for those asking the software is called GigDaddy (www.gigdaddy.xyz)
