If bitcoin have weak security, i'm sure by now bitcoin would be controlled by government or dead.
Bitcoin is still alive is the proof that bitcoin network is really strong. Most bitcoin stolen/lost usually because user fault or 3rd party service bug anyway

I secondly agree with you....bitcoin is still on and growing stronger..population keeps increasing of those using it
I agree with your statement, bitcoin will be stronger if more people use it. bitcoin is also not exposed to great effect if global economic conditions deteriorate, and the security of bitcoin was better than fiat.
More users will surely increase its strength, and governments acceptance would also strengthen BTC more. Governments indulgence is necessary for some instances, because local shops, peoples from rural areas kind of believes the government. And there acceptance would also strengthen beliefs upon Bitcoin.
However, the block confirmation time is quite long now, the transaction fee is also high, that will deter new users.
In addition to these difficulties, it is also necessary to consider the availability of conditions for new users to use bitcoin. After all, you will agree that for this not only the Internet is needed, but also good knowledge. And if we are talking about a mass transition to bitcoin, then what about people who have no education or even never used the Internet? How to deal with them?
