辺ぴ (often written 辺鄙 in fully-kanji form) is a na-adjective meaning 'remote / out-of-the-way / inaccessible' — it describes places far from urban centers, often with a hint of isolation or inconvenience. 暮らしをする ('to lead a life') is a roundabout way to say 'to live' that lets you modify the kind of life it is — 孤独な暮らし ('solitary life'). The pattern noun + をする lets adjectives describe the manner of living. スコットランド (Scotland) has long been a stand-in for remote, rugged, romantic landscape in Japanese imagination, partly thanks to literature and partly via brand associations (whisky, woolens).
