Impractical

Describing something that is not sensible or realistic; unsuited to its intended purpose or the circumstances; not feasible or workable in practice. An impractical idea often overlooks real-world constraints like cost, time, or resources, making it unlikely to succeed or be implemented effectively. It might also be an idea that is inconvenient or difficult to use.
