Very few PPL holders actually SFH anyway. Most get their licence, stick it in a drawer and never fly again. As a PPL holder, even if you just do enough flying to stay 'current' for SFH - ie 1 hr per month. That's a £300 a month 'hobby', and all you do is go round the local area. The only way to get anything out of flying is to do is as a career, or be rich enough to buy your own heli, or rich enough to spend a wad each year on worthwhile SFH trips. It all comes down to cost, and helicopter flying is damn expensive in the UK. It's a rich man's plaything, like boats and horses.
