I would support a short lockdown to help the R number reduce. Sadly, unless it reduces to 0, which it won't in a few weeks, as soon as the lockdown finishes and people start to circulate again, we will be back at square 1.
Lockdown on its own is, indeed, likely to lead to resurgence once lifted. But that is not what is proposed.
It's lockdown in conjunction with radical changes to the current shambolic centralised 'test, track, trace and isolate' operation. Where local Public Health authorities have been enabled to carry it out their success rate is much higher than the government scheme. But the government refuses to fund them, preferring to stick with the failing scheme where 'consultants' are being paid up to £7,000 a day with pitiful results.
I must confess that I am totally mystified as to what the government is trying to achieve by throwing £billions at a failed operation. They certainly don't appear to have the wellbeing of its citizens at heart.
