It's easy to do a basic install.

It's quite hard to do it right, at scale, with workload-appropriate configuration, replication, backup etc.

My point... neither Postures nor Indira, or any other blockchain solution are easy to install and maintain in a fully scaled-up, fault-tolerant, multi-node deployment
